Ahh, I see. This must be the nub of our disagreement.

The document that you quote is not a normative definition of XML.
There are many normative definitions of data models for XML, including
the Infoset and XPath.

It's a classic "chicken and egg" thing -- data models and syntaxes are
intertwined -- but in this case, XML is defined as a syntax, which can
have many data models; LMNL is defined as a data model, which can have
many syntaxes.

I don't know how to persuade you of this, but I see that Tim Bray's
written a message that will hopefully help...

Cheers,

Jeni
