OK I accept defeat willingly on this one; just incorporated your
new words.

Do we need to say somewhere that the document must be a legal XML
document first?? Otherwise there can be illegal stuff in an unused
binding and we'd still happily allow it; which IMO simply must not
be the case. Maybe XML compliance is implied somewhere?
