Douglas, I couldn't agree more with Mark's recommendation to use XQuery for constructing XML nodes, whether it be an element, attribute or what have you. And, yes that feature has been pretty well tested.
For more details, please refer to the constructors<http://www.w3.org/TR/xquery/#id-constructors>section in the XQuery spec. It lets you not only write static XML fragments, but also build dynamic XML fragments on the fly.
