Henry points out that "XML processors SHOULD provide a user option..."
implies a new feature which means we cannot do this in an erratum,
so he doesn't think we can change 1.0 to add normalization verification.

John suggests we could perhaps use some MAY wording associated
with the motherhood note.

ACTION to Paul:  Send suggested draft wording to the WG mailing list.

This spec just went back to Last Call.

ACTION to John:  Review section 2.1.3 of the POWDER spec at
http://www.w3.org/2007/powder/Group/powder-grouping/20090309.html#canon

ACTION to Paul:  Send Norm's email about using byte/character
offsets and ptr:XMLNamespace (suggesting they use a different name).

John thinks we should approve this.  Henry worries that people
will then expect that this is something from W3C, but he will
not stand in the way.

We should consider adding entries for xml-stylesheet and xml-model 
to the xml namespace document at http://www.w3.org/XML/1998/namespace.

ACTION to Richard continued.

Henry will work with Richard on NPE29.

We will then plan to issue NS 1.0 3rd Ed.

Whether we put ns prefix undeclaration into NS 1.0 3rd Ed
remains an open issue.
