The answer is "it isn't really done" ;-) As far as I can tell Commons currently has no documented way of embedding anything other than a single coordinate pair for an image, which is obviously okay for photos but pretty unhelpful for maps (or indeed aerial/satellite imagery). This is a pity, as there's some nicely curated map collections there and of course Susanna's work is likely to bring us a lot more. (I'll drop her a note about this discussion)
I put together OSDcoords, which Andy pointed out, as a quick and dirty hack to make them display with the hope that it could be transformed into machine-readable multi-point metadata at a later date; to the best of my knowledge, its the only example we have of this. Making something more usable out of it is probably beyond my cartographic expertise, but we're happy to take guidance! Andrew.
