The majority of the XML-oriented position papers at the Boston QL workshop were concerned with the latter, ie. finding things within a real or hypothetical XML document or document set. For these to be useful for your application, you'd need to 'pretend' that the database queried by your back-end search engine was an XML document or document collection. Which as you say might be overkill. I'm not aware of anything lightweight that'd do what's needed here. Maybe there's a document out there somewhere that describes the Altavista-esque +/- format adopted by the various engines objectively enough for it to be useful to ship queries around marked up as being of that type...?
