Archi the archimate modelling tool has a great way to break complex XML exchange files into small files which can be stored in git with a merge tool that understands the file format parts. Basically each entity within the exchange file format is pulled out into a seperate file and stored in git. The the actual exchange file is rehydrated and imported to the tool. When the time comes to save, a commit is made, this rips the exchange file back into discrete files, finds the ones that changed and saves them, then git commits them.
