Then the document is illegal.  Namespaces can essentially be any set of characters you want.
When you replace the prefix with a namespace, you are creating an illegal XML Name as you
already stated.  Should the DOM reflect a legal XML document or should the DOM allow anything
you want to serve as element and attribute names.

Last but not least, in XSL if you use this approach you suggested for expanding QNames, then
within ElementExpressions and AttributeExpressions, you will in essence run into problems with
parsing these expressions as characters like '@' and '/' and '|' are significant and will
screw up the entire PathExpression you are parsing.
