The key words here are "usually" and "some".

In my experience, _any_ time an XML document contains
a <!DOCTYPE ...> declaration (except for the minimal --
and useless -- <!DOCTYPE rootElement SYSTEM>) it causes some
sort of interoperability problem.  You can _usually_ configure
_some_ parsers to process docment type declarations in a consistent
way that's appropriate to the task at hand, but not always.
