Both Norm and Henry have reviewed it on the Tag list:
http://lists.w3.org/Archives/Public/www-tag/2008Feb/0050
http://lists.w3.org/Archives/Public/www-tag/2008Feb/0053

Henry doesn't think there is anything the XML Core WG
needs to do about this.  Neither does John.

---

XML would have to change for CURIEs to do what they want to do.

The key issue with CURIEs is the restriction on name start
characters for the value of ids (which is now an NCName).

Henry asks us to consider changing the type of an id attribute
from NCName to NMTOKEN.

John is opposed to allowing identifiers to be numbers.

John says accepting xyz:123 as a name is one thing, but 
accepting 123 as a name would be (more) unacceptable.

Norm:  If we allow xyz:37 as a valid QName, then we
would need to allow <37> to be a valid start tag, and 
that's unacceptable.

Norm: even if we change the type of an id attribute
from NCName to NMTOKEN, we wouldn't solve the CURIE
problem because we still wouldn't allow xyz:37 to 
be a QName which is what the CURIE spec requires.

Norm clarifies that, while you can undeclare namespaces in
the infoset, you cannot serialize in XML 1.0 an infoset that
undeclares a namespace prefix.

We could process an erratum to NS 1.0 that adds the ability
to undeclare a namespace prefix in NS 1.0.

We would probably make NS 1.0 a copy of NS 1.1 with appropriate
minor changes.
