That is a good suggestion Dan. Thank you. However, that XPath returns a
simpleType not a QName (which is what I desire).

I wrote an XSLT program which returns the appropriate QName. See below. It is
awful (i.e., it is a very complicated solution to a very simple problem). I am
hoping that someone can provide a simple solution.  /Roger
