What would be best is that the preparsed dtd's could be called with
simple parameters to decide retrieve a list of allowed contents or a
simple boolean question:

        isThisAllowed("LaTeX-Article", "tabular", "footnote")

this should return true. Or someting like:

        getWhatsAllowed("LaTeX-Article", "tabular")

which should return a vector<LString> for example.

Thus we could have a simple interface to solve all our problems.
All we'd need to know is what the current paragraph style is and what
style the user wants to add.
