It was fun to go back and look at that code again. I tweaked
the XML parser a few years ago (to add CDATA and PI processing)
and found it a very educational experience.
Incidentally, there is a "buglet" in XML-LANGUAGE; the word
ATTR-NAME is not placed in the object context, so using
XML-LANGUAGE creates that word in the global context...

I've found it so. Even the "enthusiastic disagreements" usually
stimulate me to learn something -- or at least think things thru
more clearly. ;-)
Incidentally, I've been using "near-XHTMl" (HTML written with
XML syntax -- quoted attributes, self-delimited empty tags...)
for a few years now, and have yet to see any problems with it.
One of my motivations was to be able to use parse-xml on my
HTML documents...
