processor, but I would be rather surprised if the call mechanism allowed you
to B  return a string containing lexical XML, and implicitly parsed that XML
and turned it into a tree of nodes. That conversion needs to be done e B 
explicitly by calling an XML parser, either from the C# before returning from
the extension, or from the XSLT code after returning.
