It appears to me that your application has a need that was not an issue
for the usecases addressed by Schema or XPath-2.0.  So, you are safe by
picking whatever QNames you want!  (Just avoid using "xml" for a prefix,
in case your QNames ever get serialized into textual XML, --- "xml", and
other prefixes starting with "xml", are reserved by the Namespaces Rec for
future W3C-sanctioned use.)
