Can anyone on the XML Core WG state whether the document at the URL described below has any degree of normativeness whatsoever? This is really a question for John Cowan or Tim Bray.

Underlying XML is a data model. That data model is set forth at:
http://www.w3.org/XML/Datamodel.html
It is not happenstance that all of the "data models" that you cite,
PSVI, XPath, DOM, are based on the presumption of a tree. The tree model
underlies all those "data models" and its presence was not a matter of
chance (or choice). (LMNL does not use that model but then it is not a
XML data model. It is a data model that can model documents based on the
XML data model.)
