XSL WG Comments on Namespace in XML 1.1

1. Section 1. 
"Names from XML namespaces may appear as qualified names, which may
contain a single colon separating the name into a namespace prefix and
a local part. The prefix, which ..."

Should the second sentence say something about the namespace of a name
without a prefix?

2. Section 2. 
"[Definition: A namespace is declared using a family of reserved
attributes.  Such an attribute's name must either be xmlns or have
xmlns: as a prefix. ..."

In the second sentence, xmlns: should be changed to xmlns.

3. Section 5.1
"The attribute value in a namespace declaration for a prefix may be
empty. This has the effect, within the scope of the declaration, of
removing any association of the prefix with a namespace name. Further
declarations may re-declare the prefix again:"

The ability to undeclare namespaces creates the possibility of
creating InfoSets that cannot be serialized as XML 1.0. We need to
understand how the InfoSet will tackle this problem: will there be
different InfoSets for XML 1.0 and XML 1.1, or will there be a single
InfoSet with rules for mapping it to both XML 1.0 and 1.1?

4. Section 7.
"Some characters are disallowed in URI references, even if they are
allowed in XML; the disallowed characters, according to [RFC2396] and
[RFC2732], are the control characters #x0 to #x1F ..."

The sentence implies control characters #x0 to #x1F are allowed in
XML, but only #x9, #xA, and #xD are allowed in this range.

5. Section 7.
Should there be reference to the Internet-Draft on IRI's? 

6. Appendix A.
A reference to XML 1.1 should be added.
