I originally included a lot of "DTD" support in JUMBO to try to deduce how
to process the document. I've spent the weekend removing it in favour of:
	- stylesheets
	- namespaces
For most documents the DOCTYPE will look something like (example from the
HTML source of the XLL draft 970731):

<!DOCTYPE HTML PUBLIC '-//W3C//DTD HTML 1996-01//EN' 'system.dtd'>

The Name HTML simply says that the root element of the document must be
HTML (I assume that a validating parser will throw an error if it isn't).
The FPI may be usable by some people, but that's another issue. The
SystemID isn't much use on its own.

DOCTYPEs will be problematic with WF documents from more than one namespace.
