Even _with_ 20/20 hindsight I don't think anyone's devised
a way to unambiguously and reliably identify mixed content
without a DTD or some other external device that provides
vocabulary-specific information.
For all the quirks and seemingly-bizarre whitespace rules
in SGML, it's one of the few markup technologies where
whitespace handling tends to Just Work (as long as you
follow best practices like "avoid pernicious mixed
content").
