Jose forwarded a message from Philippe:
http://lists.w3.org/Archives/Public/public-xml-core-wg/2007Feb/0008

What is the relationship between C14N 1.1 and XML 1.1?

We see no reason that C14N 1.1 couldn't be used with XML 1.1.
Philippe would like us to make this clear in the C14N 1.1 spec.

Namespaces 1.1 does allow the undeclaring of a namespace prefix
which might cause problems for C14N.  But then we decided there
might already be problems with C14N and NS 1.0 (not preserving
prefixes in some cases--what JohnC calls qname-correctness).

JohnC suggests:  If a namespace is declared in the input, then 
it must be declared in the output.

John points out that it's not clear how you generate an xpath 1.0 
model for an XML 1.1 document.

ACTION to JohnC:  Send email to the list summarizing the issue
and your suggested solution.

Mike Kay thinks the defn of XML Resource Identifier is too vague. 

PLH/Ian gave their opinion at
http://lists.w3.org/Archives/Public/public-xml-core-wg/2007Feb/0006

Paul thinks an RFC is easier and more appropriate.

Paul, John, Norm don't think copying it in several places is a solution.

It seems we have three choices:

1.  a mini-Rec
2.  an RFC
3.  XML 1.0 Fifth Edition
4.  and the defn to Infoset and come up with an new edition

We were thinking we could produce a new edition of the Infoset 
that includes our definition XML Resource Identifier and change 
the reference in XML Base from one to XLink to one to XML Base 
and also change XLink to reference the new definition in the 
Infoset edition.

We should also issue PEs for XML 1.0 and 1.1 about this.

Then John points out the definition of XML Resource Identifier
is basically in the XML spec without actually using the term.
He suggests we just add the term to XML 1.0 5th Ed and XML 1.1 3rd Ed.

Norm suggests we provide a more crisp defn of XML Resource 
Identifier and say processors "should" check it but don't
have to.

ACTION to Norm:  Draft a better definition of XML Resource
Identifier.

We'll let this sit for a couple weeks and then decide 
more exactly what to do.
