product classes, "support some version of XML" (detailed review of section 1. Introduction)

The draft says:

"Implementations that support XHTML5 must support some version of XML"

The XML spec defines conformance of XML documents and conformance
of XML processors. It doesn't define "implementation support".

Just before this 1.3.2. Dependencies section, there's an enumeration
of HTML 5 product classes: user agents, authoring tools, etc.
Is "implementations" intended to refer to all of them? Perhaps
that's clear enough, though I'd prefer it were stated explicitly.

It seems to me that the dependency on XML will come up naturally
in the relevant part of the spec (along with the references
section) and it's not useful to state it in the introduction.

If this sentence isn't struck, please re-phrase it in
terms of "conforming XML processor".
