Bzzt. Names starting with "xml" are reserved, yes, but this is a semantic
reservation ("don't use it unless it's for the purpose we say it's for), not a
well-formedness constraint. The only constraint of the sort you are talking
about is on a processing instruction target. That is,

  "<?xml foo?>"

is definitely not allowed, but

  "<?xml-foo?>"

and

  "<foo xml='bar'>"

are allowed.
