Draft 3 July 2004, Jim Moore
Meeting #46 of ISO/IEC JTC1/SC22/WG9 was colocated with the Ada-Europe conference.
Conference and venue information can be found at the conference web site.
The announcement and preliminary agenda for this meeting were circulated as N436. The detailed agenda was distributed as N438.
The meeting was called to order at 9:10 am.
Erhard Ploedereder welcomed the group in behalf of our host, the Ada Europe conference.
The final agenda had been distributed only a few days before the meeting. So the convener spent a few minutes going over the substantive changes since the prior distribution. The agenda was approved without objection.

| Prior Discussion |
From Minutes of Meeting #43 [N418]: Clyde Roby made a presentation on a method to deal with APIs. Clyde's presentation will be posted on the WG9 web site as N419. There were some comments regarding the assurance that SIGAda has the proper rights to republish the artifacts. Erhard noted that an API may be an Ada binding to an implementation in another language or a standalone Ada implementation. Jim noted that "Stamp of Approval" concept might lead to anti-trust problems. "Choosing or Judging" would be an antitrust problem. This should be done under WG9 auspices. Erhard noted that there should be a long-term program to collect APIs; and a short-term program to select some APIs into Ada 200Y. Make sure that this is clear to participants. Only a few will be selected for the Ada Amendment. From Minutes of Meeting #44 [N428]: Clyde Roby reported on the formation of a SIGAda API WG at WG9's last meeting. This work is proceeding. Information has been posted to a web page. Material from previous groups is being gathered. They are starting work on CGI and XML interfaces. XML seems to be active also. Some issues remain regarding licensing. API WG will be formally approved soon. SIGAda is looking at an organization to provide comments on WG9 documents. They should collaborate with the convener and the Ada-Europe liaison representative on a procedure for doing this. Comments must be vetted and formed into a consistent position. It was noted that comments on technical documents are generally unwelcome at the WG9 level and should be submitted at the Rapporteur Group level. The convener suggested that the liaison organizations might want to designate formal representatives to the RGs. From Minutes of Meeting #45 [N434]: Clyde Roby (SIGAda APIWG Chair): There was a meeting of the APIWG. One of the major subjects was the method for progressing APIs toward standardization. There is a desire to develop the APIs outside the standardization groups so that they can be developed quickly and then transpose them into the standardization process, perhaps as TRs. There may be something to submit by summer. SIGAda Representative: We had previously mentioned that AIs might be circulated to the liaisons for review. SIGAda is ready to receive them when appropriate. |
| Report | Currie Colket thanked the participants in WG9 who provided briefings at the 2003 SIGAda Conference on the subject of the changes anticipated in the amendment to the Ada standard. |

| Report |
Reconsideration of JTC1 Confirmation of ISO/IEC 13814Every year, JTC1 reviews its work programme, notably those standards approved five years prior, hence requiring action to confirm, revise or withdraw. In advance of this consideration, WG9 is required to make a recommendation that is forwarded to SC22 for endorsement. Normally, SC22 endorses our recommendations, JTC1 approves them and ISO Central Secretariat implements them. The process is lengthy but normally routine. This year, however, JTC1 voted to confirm ISO/IEC 13814 rather than withdraw it as requested by WG9 and SC22. The SC22 Secretariat conducted a letter ballot authorizing it to request that JTC1 reconsider its action. Accordingly, the request was sent to JTC1 and JTC1 has responded by circulating a letter ballot (J1N7405) to withdraw the standard. The ballot ends 22 June 2004. The problem would not have occurred if two National Bodies represented in WG9 had not voted to confirm at the JTC1 level after voting to withdraw at the WG9 and SC22 levels. This underscores the importance of WG9 delegates remaining in touch with their national bodies. Format of Ravenscar Guide The JTC1 Secretariat has informally advised the SC22 Secretariat that the University of York report that forms the body of PDTR 24718, Ravenscar Guide, must be re-drafted into the ISO document formal prior to DTR balloting. I have asked ISO Central Secretariat for a position on this matter. Redrafting has both good and bad features. Obviously, it requires work from the document editor, but it would serve to reinforce the position that the ISO document is distinct from the freely available York report. The most recent response from Central Secretariat advises that the Ravenscar report, as is, may be packaged as Clause 4 of a format that includes boilerplate for the first three clauses. Upcoming SC22 Plenary Meeting The next plenary meeting of SC22 is in Korea. The expense to travel there is high and our business for the meeting is slight. Therefore, I have decided not to attend. If any member of WG9 wishes to represent WG9 at this meeting, I am willing to confer with him or her on the subject. Moving forward with the Amendment The ARG is proceeding with the preparation of the Amendment to the Ada Language Standard in accordance with the instructions previously provided by WG9. As directed by those instructions, the ARG Rapporteur has submitted a document providing a statement of scope which will be considered at this meeting. It is important to note that approval of the scope does not imply approval of all of the AIs which contribute to the document. Time is short, though, because the ARG is scheduled to begin circulating informal drafts of the Amendment for comment soon after this meeting. Furthermore, they are requested to complete a final draft by Spring of next year. For that reason, it is important that outstanding issues be quickly resolved. Therefore, I am preparing for the following possibilities:
In both cases, I will conduct email ballots of WG9 to reach a decision. In the second case, I will invite contending parties to submit proposals to WG9. An email ballot will choose among the proposals -- without change. This approach is necessary to move forward in preparing the Amendment on the agreed schedule. |

| Resolution 45-5: |
WG9 delegates to its HRG the authority to perform comment disposition on the New Work Item proposal ballot for the Ravenscar Guide as well as its PDTR registration ballot, and to revise the draft document appropriately. The convener of WG9 is authorized to review the comment disposition, determine if consensus has been achieved on the disposition of the comments and the revision of the document, and forward the resulting draft for PDTR approval balloting. Status: CLOSED. Convener performed the directed actions. In error, the new SC22 Secretariat initially forwarded the document for DTR ballot, but quickly corrected the error. PDTR balloting is due to close on 11 June 2004. |
| Resolution 45-6: |
WG9 endorses the use of Technical Reports, International Workshop Agreements, or other light-weight documents to record and publish agreements on API definitions, while retaining the possibility for eventual international standardization.

| Report |
Email from Pascal Leroy, 2 June 2004: The ARG met in San Diego, CA, USA, in December and in Phoenix, AZ, USA, in March. As is customary, the meetings were mostly devoted to amendment AIs. A number of the key amendments (e.g., mutually dependent types, interfaces, improvements related to access types) are now ready for consideration by WG9. At its San Diego meeting, WG9 considered the best way to proceed with standardization of APIs, and recommended the use of Technical Reports or International Workshop Agreements to reach agreement on APIs (see resolution 45-6). As a consequence of this recommendation, the ARG discussed the applicability of such a light-weight process to AI95-00302-01 and -02 (Container library), an amendment which had been around for some time and for which a consensus was hard to find. However, after much discussion the ARG concluded that starting an alternative standardization process would send the wrong message to the Ada community, and that secondary standards have not been very successful in the past. In order to give this AI another chance without wasting ARG time, a subcommitee was created and tasked to look at the various proposals and come up with a recommendation to the ARG. Before the Phoenix meeting the subcommitee presented its report to the ARG: it had constructed out of the competing proposals a new AI that was small enough that it could be included in the Amendment, and still functional enough that it could cover most user needs. This AI was extensively discussed at the Phoenix meeting (the ARG spent one full day on it) and a consensus was finally reached. So at this point it appears that AI95-00302-03 will likely be part of the Amendment, and that there is no need to start an alternative standardization process. At the Phoenix meeting, the ARG also reviewed so-called "dormant" AIs, i.e., AIs that were still open, but had not been worked on for a long time. There was a long list of these AIs. Many of them were voted "No Action", some of them were approved, a few were reactivated. This review was necessary to ensure that no important topic was unwittingly left out of the Amendment. At the San Diego meeting, the ARG had a long discussion of AI95-00285 (Support for 16-bit and 32-bit characters) but couldn't reach a conclusion. It was decided to ask WG9 for guidance. To put things in perspective, here is the history of this AI: 1 - AI95-00285 was prepared in 2002 based on two user requests (posted on ada-comment): one was to add support for Latin-9; the other was to add support for 32-bit characters (Wide_Wide_Characters) at execution. 2 - The first discussion of this AI took place at the Bedford meeting (October 2002). Regarding support for 32-bit characters, the minutes state that "we agreed that [writing character literals of Wide_Wide_Character in Ada source] should be allowed" and they note "that there is a push in SC22 to allow full wide characters in identifiers". Regarding support for Latin-9, some members found "that ... it is weird to treat a Latin-1 character as if it is Latin-9". 3 - At the Padua meeting (February 2003), the AI author argued that "Latin-9 is not widely used" and proposed "that we ... simply go to 16-bit source code". A number a technical issues (character classification and case folding rules, in particular) were discussed, and it was noted that "the Unicode people have rules that we could follow". The intent of the proposal (do not support Latin-9, support 32-bit characters in the source and at execution) was unanimously approved. 4 - At the Toulouse meeting (June 2003), some members mentioned that the current write-up was perhaps not acceptable to their SC22 delegation. During the summer of 2003 a number of issues were discussed by email. Most of them were of a technical nature (e.g., characters allowed in numeric literals, normalization forms, etc.). However, a significant non-technical issue was raised in this discussion: referencing Unicode, which is not an ISO standard, in the Amendment was considered problematic by some members. 6 - At the Sydney meeting (October 2003), the Rapporteur presented to the group the essence of the email exchange that had taken place during the summer. The minutes explain that some countries "won't allow reference to Unicode in the standard ... However, 10646 says very little about upper/lower case, character classification, etc. ... Our options: just drop improved character support ... or do it with Unicode ... We decided to go ahead using Unicode." 7 - At the San Diego meeting (December 2003), the technical issues raised by the email discussion were addressed and resolved. The issue of referencing Unicode was still very controversial. The AI as presented at that meeting "tried to use ISO 10646". Because ISO 10646 does contain references to Unicode (both in normative text and in non-normative text), this was effectively providing a means to use the character classification and case-folding rules described by Unicode. Some members were unhappy with this state of affair, though, and proposed to use TR 10176 instead because "this report gives the international agreement for character sets". Unfortunately, "it doesn’t cover things like case conversion". After an inconclusive discussion, the minutes note that "we have to reference 10646 for the upper case; the open question is to reference 10176 to composition of identifiers or 10646+Unicode recommendation. WG9 needs to decide that; both have problems from our perspective". As directed by WG9, the Rapporteur has prepared a document presenting the scope of the Amendment. In general, the AIs mentioned in this document either have either been approved by WG9 or are very close to approval. However, some of them still require technical refinement before the ARG can decide whether to include them in the Amendment. Others are controversial. In both cases, the AIs have been included in the scope document with the understanding that this inclusion is provisional. The ARG has its "usual" motion for the June meeting for approval of a series of AIs. See the list below. A pointer to retrieve the AIs is included. The Rapporteur proposes the following list of members for the ARG: Baird, Baker, Barnes, Brukardt, Burns, Dewar, Dismukes, Duff, Ishihata, Leroy, Michell, Ploedereder, Rosen, Schonberg, Taft, Tokar. The cited AIs can be retrieved from the ACAA Web Site for AIs: http://www.ada-auth.org/cgi-bin/cvsweb.cgi/AIs/ Amendment AIs: AI95-00217-06/08 2004-05-21 -- Limited With Clauses
Normal AIs. AI95-00148-01/03 2004-05-21 -- Requeue of protected entry calls
AI95-00245-01/03 2004-05-24 -- Consistency of inlined calls
Email from Pascal Leroy, 7 June 2004: Following the comment from France about AI 286, the Rapporteur has decided to withdraw this AI from the list submitted to WG9 for approval at the upcoming meeting. This AI will be sent back to the ARG in order to study the French proposal. |
| Discussion |
We reviewed the continuing technical and political disagreement in SC22 regarding character set coding. The convener stated that he was concerned that regardless of the approach that take in our amendment, the amendment might become caught in disagreement at the SC22 level. We are now close to agreement on an approach to character set coding that will satisfy the concerns of all parties, notably the Japanese national body, who regard this as a particularly important issue. We agreed on an approach that authorizes the convener to communicate with the SC22 Secretariat to table a resolution requesting agreement on our chosen approach prior to progressing the amendment to the level of SC22. This will permit SC22 to undertake discussion without getting our amendment trapped in the process. The convener reviewed the draft of the letter that he has prepared for SC22. The ARG Rapporteur and the HOD of Japan agreed to resolve a final technical issue and advise the convener how to modify the draft, which will be logged as N441. It was noted that the document describing the scope of the amendment [N437] serves to implement resolutions 42-7 and 45-6. The ARG does not see a need for any mechanism other than the amendment to provide standard APIs. |

| Background | WG9 N417: Charter of the ASIS Rapporteur Group (ASISRG) |
| Prior Discussion |
From Minutes of Meeting #41 [N400]: ASIS RG is considering the preparation of a New Work Item Proposal to revise and extend ASIS to keep pace with Ada 2005. The ASIS RG may reconsider some of the design goals for the specification. From Minutes of Meeting #42 [N409r]: Currie Colket reported that the ASIS RG has begun planning for the development of amendments to the ASIS standard in coordination with the planned amendment to the Ada standard. Steve Blake cannot continue as project editor; however, he has agreed to continue serving until a replacement is found. From Minutes of Meeting #45 [N434]: Greg Gicca was nominated as co-editor of ISO/IEC 15291. |
| Report | The nomination of Gicca as a co-editor has been tabled for approval at the SC22 plenary meeting in September. |
| Discussion | The Rapporteur was asked if the ASIS RG is preparing a work item for revising the ASIS standard. The Rapporteur accepted Action Item 46-1 to draft a new work item prior to the Atlanta meeting of WG9. |

| Background | WG9 N416, Charter of the HRG |
| Open Item |
Resolution 45-5: WG9 delegates to its HRG the authority to perform comment disposition on the New Work Item proposal ballot for the Ravenscar Guide as well as its PDTR registration ballot, and to revise the draft document appropriately. The convener of WG9 is authorized to review the comment disposition, determine if consensus has been achieved on the disposition of the comments and the revision of the document, and forward the resulting draft for PDTR approval balloting. Status: CLOSED. The HRG and the convener performed the directed actions. In error, the new SC22 Secretariat initially forwarded the document for DTR ballot, but quickly corrected the error. PDTR balloting is due to close on 11 June 2004. |
| Prior Discussion |
From Minutes of Meeting #40, [N389]: The HRG ... discussed the continuing role of Annex H of ISO/IEC 8652. They discussed the desirability of changing its title to High-Integrity rather than Safety and Security. The HRG might recommend that the fourth section of Annex H should be reworked to better fit with the recently completed TR 15942. They also considered tracking the usage of relevant pragmas implemented by various vendors. It is understood that the HRG may work with the University of York or other institutions in obtaining material that might be incorporated into a Technical Report. From Minutes of Meeting #43 [N418]: HRG met in October and finalized the Ravenscar Guide. We await WG9 acceptance of Ravenscar AIs to complete our Guide. This will then be published as a University of York report and offered to WG9 as a Technical Report. The procedure for treating the NWIP will be to attach the draft report to the NWIP and ask for immediate PDTR Registration. Email from Alan Burns, 15 May 2003: Now that the Ravenscar report has been completed and `published' by York [N424], I guess we would still like it to become an ISO technical report. I think, going on what you said before, this needs a new work item [N426]. From Minutes of Meeting #44 [N428]: The HRG met in October at York University. A paper regarding guidelines for the use of the Ravenscar profile was published. It will be submitted to be processed as an ISO/IEC Technical Report. The HRG met again on June 16 to discuss possible changes to Annex H. It concluded that the title of the annex should be changed from "Safety and Security" to "High Integrity Systems." The HRG Rapporteur was asked to summarize why the title should be changed. He replied that "High Integrity" has become the accepted name for this category of issues; there is nothing in the annex related to security; and the current contents are broader than safety. Feedback on the proposed name change was favorable. The HRG will submit an AI to change the name. The Convener noted that the draft Technical Report will be attached to the New Work Item for concurrent PDTR registration. The New Work Item calls for a Type 3 Technical Report -- a document that is inherently unsuited for standardization. It was noted that any typographical errors in the Report should be fixed prior to submission. From Minutes of Meeting #45 [N434]: So far, there have been no suggestions for substantive change in the report providing guidance on the usage of Ravenscar. If no comments come from the ongoing concurrent NP and PDTR registration ballots, then the document will be forwarded as is for PDTR approval ballot [N435]. SC22 N3724, SC22 Secretariat, 11 March 2004: Letter Ballot for Approval of PDTR 24718, Guide for the use of the Ada Ravenscar Profile in high integrity systems DUE DATE: 2004-06-11 |
| Report |
Email from HRG Rapporteur, Alan Burns, 24 May 2004: HRG has submitted its report on Ravenscar to WG9 for processing, and awaits the outcome of the various votes required for the report to become an ISO document. |
| Oral Report | The HRG Rapporteur reported that PDTR 24718 was approved. There appear to be no comments but there is some concern that the balloting report might be incomplete. In any case, the document will be prepared in the format determined by the convener (see Convener's Report) and submitted for DTR ballot. There have been no HRG meetings since the last meeting of WG9. |

| Prior Discussion |
From Minutes of Meeting #43 [N418]: Draft 3 of the Amendment document is available at the ACAA Web Site. This document includes all of the AIs approved by the ARG as of the Bedford meeting; thus it is a snapshot of a work-in-progress rather than a finished document in any way. Work on the accompanying integrated Ada Reference Manual is proceeding slowly due to a lack of funding. Some work has been accomplished, but much more remains to be done. At this time, priority is being given to developing the proposals over editorial presentation of them. From Minutes of Meeting #44 [N428]: Another draft of the amendment was posted in March. The content includes anything approved by the ARG (even if not yet approved by WG9.) There have been no updates to the ARM because of lack of funding. It is important to do this to make sure that there are no errors in integrating the amendment into the base standard. When the Corrigendum was developed, some errors were discovered at this stage. There was some discussion of the advisability of updating the rationale. Leroy suggested that books may be more useful to end users than the rationale. Taft suggested that we may not have to produce as many products for end users -- perhaps some existing paper and other products could be combined. A web site might the appropriate vehicle. Ploedereder suggested that individual rationale articles, devoted to specific issues, could be published in the Ada Journal. They could then be collected in a book. The schedule for the amendment includes: WG9 approval of scope in spring 2004 and approval of the wording of the amendment in spring 2005. From Minutes of Meeting #45 [N434]: Regarding the schedule for the amendment, the ARG Rapporteur said that the ARG will distribute a list of AIs, probably in the spring of 2004, so that they can be approved at the June 2004 meeting of WG9. Pascal is willing to take an action item to prepare a short document explaining how the AIs relate to one another. |
| Report | The project editor has been looking for funding to prepare a text that would combine the various components of the Ada Reference Manual into a book. Ada Europe is considering funding the work and publishing the book. |
| Discussion | The convener noted that the decision to publish ISO/IEC 8652 as a merged document or separately as base standard, corrigendum, and amendment would be a business decision made by ISO Central Secretariat. If Central Secretariat requests a merged document, the project editor should be prepared to provide one by merging the official ISO standard, corrigendum, and amendment. |

Status: OPEN. The recommendations above were endorsed by SC22 Resolution 01-07 at their September 2001 plenary meeting. They have been forwarded to JTC1 for approval (during 2003) and implementation by ITTF (during 2004). This year, however, JTC1 voted to confirm ISO/IEC 13814 rather than withdraw it as requested by WG9 and SC22. The SC22 Secretariat conducted a letter ballot authorizing it to request that JTC1 reconsider its action. Accordingly, the request was sent to JTC1 and JTC1 has responded by circulating a letter ballot (J1N7405) to withdraw the standard. The ballot ends 22 June 2004. |

There was no unfinished business.
[Agenda]
Although there was no new business, the HOD of France asked to review the document describing the scope of the amendment [ N437 ]. The French NB has some concerns about AI-284 which would provide a short list of language keywords that are not reserved words. It was determined that France should prepare an alternate proposal for AI-284 by July 19 (Action Item 46-2). The convener will then conduct a 30-day email ballot to choose between the two alternatives in accordance with the procedure described in the Convener's Report.
The US HOD mentioned some concerns of the "security" of the AI proposed for "containers". The ARG Rapporteur agreed to discuss the concerns with the US HOD.
The convener was requested to post a project plan on the WG9 web site showing the schedule and a summary of the amendment. (Action Item 46-3)
