This is a formal response from the XML Core WG to your comments on the
Namespaces in XML 1.1 last call working draft.

If we haven't heard from you by the end of Monday December 9th, we
will assume for the purposes of our planned CR request that you have
no objection to our resolution.

Summary: accepted

This has been clarified.  We have removed appendix B, and adopted the
"expanded name" terminology of XPath, and explicitly state that

 - the namespace name for an unprefixed attribute name is always null;
 - the interpretation of unprefixed attributes is determined by the
   element on which they appear.
