DOCBOOK: Docbook and linguistics

Hi all.

I am not sure if I am writing to the right list (perhaps
docbook-apps is more suited?); please flame me if I'm wrong.

Does anyone of you have experience in using Docbook (or maybe
just not DocBook) within linguistics? What I need are taggings
for sentence examples, linguistic categories (like NP, VP and
the like), syntactic trees, and stuff like that.

    Cheers,
    Marco
