Jeff, this seems an orthogonal concern to what was being responded to?
The issue (at that point) had little to do with support of relational
operations.  Rather, the question was (or seemed to be), what was the
equivalent of some relational concepts in the XML world???

In any case, it seems you're stating: a document is equivalent to a
relational store if the document has enough information to be equivalent
to a relational store...  Not quite sure what that gains us?
