I think the spec is explicit, that if two calls on document() use different
URIs then you get two distinct documents back. The XPath model doesn't allow
a single node to belong to two different documents, so if the documents are
distinct, then all the nodes they contain are distinct.

To look at it another way, an entity reference creates a copy of the
referenced tree, not a link to it.
