Good catch. I forgot that. There are one or two XML parsers that blow
this one, but they're not much used. The specific BNF production is:
doctypedecl ::= '<!DOCTYPE' S Name (S ExternalID)? S? ('[' intSubset
']' S?)? '>'
External ID and system ID are both optional.
Is there anything else that stops every HTML5 document from being a
well-formed XML document?
