(Or for that matter, they fail because the remote site is down or lost the
DTD. Happened before, will happen again).

Yes. Don't do that. Either do not validate at all, or validate against a
local copy. This is common sense. I'm surprised how frequently people make
this mistake.
BTW: it's not XML's fault. URLs *identify* a DTD for the document. Nobody
says that you must actually retrieve it. Imagine every browser would GET a
document from www.w3.org to parse an HTML document.
