The only time that qnames should ever be used in content is while
describing XML tree manipulation actions for an XML parser.  Use
of qnames for anything other than that is extremely poor design
because they don't have a defined mapping outside of XML parsing.
Qnames in attributes should be explicitly forbidden by the W3C
outside of stylesheets and XSLT.

Use URIs.  If you need short names, then define short URIs
or a single base URI that encompasses all of those naming
schemes using relative identifiers.
