I'm having a tough time finding where I can use commands to replicate the ticky-box behavior of the GUI to say "use the Java parser" and "parse against the DTD".
What I want to be able to do is parse a given document against three different DTDs, validating it each time. It needs to parse against the specific DTD because these DTDs have fixed attributes, and if I don't parse the documents on load, the fixed attribute won't be there and validation will fail.
