This sounds a lot like what achavi is doing right now. Note that with the introduction of the famous 'attic' concept, augmented diffs are nowadays simply translated into a plain Overpass QL query and calculated on the fly. This also means that you don't have to stick to a minute interval or a global scope as before: you're free to provide time intervals matching a changeset (like achavi does), or restrict the adiff to a certain bounding box or even some nodes/ways/relations with certain tags only. There's no XSD around, the wiki page should answer most questions, though. In general, the Overpass Dev list would be a good place for more details and discussions.
