RE: Subtype/inheritance in XML, how does XSLT handle i

The "subtypes" and "inheritance" are in your mind: XSLT doesn't know that
this is the way you interpret the semantics of your XML. As far as XSLT is
concerned, you're simply following references. 

Before embarking on code I think I would want a better specification of the
problem. For example, are the names A and B, doc and v1 fixed, or do you
want something more generic? Can there be multiple levels of indirection?
Could <doc> itself contain a ref attribute that points somewhere else? Might
there be namespaces involved?
