I think adding a DTD that correctly defines XSPF would be no problem,
i.e. not require a change in the spec. That would be a candidate
for the notes wiki page in my eyes if it was possible...

DTD will be neither a super- nor a subset. For the doctype thing
it should be superset so we don't make valid XSPF files as invalid.

That said my vote is against the doctype line. I'm not even sure
if a DTD file has any use at all then.

Please explain that further, not sure what you mean.
