Forgive me for asking what may seem like a stupid question, but what's
not XML compliant about them now, and why do we care?  The text is
only ever going to parse as SGML (not XML) so I guess I don't see why
it matters.  I don't really object to the proposed patch but I guess
I'm not sure what it accomplishes.
