Oh, so XML documents that doesn't have a resolveable DTD is not only invalid
but also ill-formed. That seems kind of unneccessary... Especially
considering all the DTD-based documents out there already, and external
tools which require the DTD doctype to be defined. We'll have to inspect the
documents doctype before running XProc scripts on them. Oh well...

For now I guess I'll try going for your first choice of creating an empty
DTD (or make a copy of the actual DTD) and insert an absolute URI to it in
the documents. Ugly, but it will work.
