ok, I see. Well, this option-setting mechanism isn't currently part of the
API. Would it be, I probably wouldn't ask the question.

indeed.

I don't understand that. Again, generating a document object doesn't involve
any state that justifies a parser *object*. Even the parser options you are
talking about could well be put into the 'create_document' function arguments
(with sensible default values).
