I find this last paragraph pretty hard to read.  Assuming that the 
point is to convey what IANA is not involved in and why, how about this 
alternate wording and you can tell me if I've overlooked some other 
point:

"WebDAV uses namespaces to disambiguate property names and XML elements 
(used in property values and more generally in XML request and response 
bodies).  Any WebDAV user or application can define a new namespace 
with which to declare custom properties or XML elements.  IANA does not 
need to manage such namespaces, property names or element names."

Or even simpler:

"XML namespaces disambiguate WebDAV property names and XML elements.  
Any WebDAV user or application can define a new namespace in order to 
create custom properties or extend WebDAV XML syntax.  IANA does not 
need to manage such namespaces, property names or element names."

Also I think it's readable enough to have this section whole without 
subsections as it's pretty small.

The rest of the changes I am fine with and I've heard no other 
suggestions so I'll apply those changes.
