Despite this, I've never found a PDF document that didn't work with xpdf or evince.

has really ugly fonts in xpdf/evince/gv/mupdf. Do you regard this as a PDF document?
As far as I understand it is not a valid PDF document since it uses fonts that it does not embbed. However, neither of those programs shows any warning to user about this so they conclude that xpdf/evince/gv/mupdf are just broken.
