Re: access to namespace prefix

Jeff:

Finally getting around to saying thanks for the reply.  I hadn't 
carefully read the namespace parts of the XML documents, and assumed 
that namespaces were not quite as flexible as they are (ie. I thought a 
prefix/namespace pair were fixed for an entire document).  Now I 
understand why I was asking the wrong question.

Thanks - Mark
