1) The definition of NCName references to W3C XML Schema Part 2
rather than "Namespaces in XML".
A non-terminal symbol NCName occurs in the EBNF for the compact
syntax in C.2 (which is added by Amd1). This non-terminal is defined
using W3C XML Schema Part 2. However, it should be defined using
"Namespaces in XML" (W3C Recommendation), since NCName as defined in
W3C XML Schema allows leading/trailing whitespace. Such
leading/trailing whitespace cause significant problems to the
definition of quotedIdentifier, CName, and nsName, which rely on
NCName.
Note: In the OASIS committee specification for the RELAX NG
compact syntax, the definition of NCName relies on "Namespaces in
XML".
2) ISO/IEC 10646 is not referenced.
Since the compact syntax has an escape mechanism for ISO/IEC
10646 characters, ISO/IEC 10646 should be cited as a normative
reference but it is not.
3) It does not make sense to mention an alternative syntax in
Clause 5.
The last sentence of Clause 5 (which is added by Amd1) is "An
alternative compact syntax is described in Annex C." However, Since
Clause 5 of 19757-2 is "Data model", this sentence should appear at
the end of Clause 6, which is "Full syntax".
4) The media type for the compact syntax has already been
registered.
C.7 (added by Amd1) says that the media type for RNC is "being
reviewed by the IESG". However, it has been already registered at
IANA.
5) W3C XML and W3C XML-Names do not have to be added.
[4] W3C XML and [5] W3C XML-Names were introduced by Amendment 1, but
they are normative references of 19757-2 already.
