The format is pretty standard .osm XML. It currently outputs a visible attribute for every object. Apart from that everything should be standard[1] and modeled after the tool that writes the planet except that each element may occur multiple times. There are only two things to look out for: It is not "pretty-printed", so everything is just one huge line (I know that some people do line-based parsing but that won't work here) and as there's old data mixed in not every element has uid and user attributes. Let me know if you have any questions or if a format change would help in any way but I believe the current format is pretty normal and should be parseable by almost every tool that already parses .osm files.
