As many of you may know, MultiContent Revisions are coming soon (October?) to a wiki near you. This means that we need changes to the XML dumps schema; these changes will likely NOT be backwards compatible.

Initial discussion will take place here: https://phabricator.wikimedia.org/T199121

For background on MultiContent Revisions and their use on e.g. Commons or WikiData, see:

There may be other, better tickets/pages for background; feel free to supplement this list if you have such links.
