As "unstable" changes and "latest" becomes no more, these sorts of links should be updated to reference the approximate section they intended to reference at the time of writing.
This change tries to link up the relevant bits for the time of the proposal, though it's not a perfect match. Some MSCs were brought into the spec before an API version could be assigned to the "old" text, so github permalinks are used instead.
- Authority part semantics are no more prescribed; authority part has
defined syntax but reserved for future use.
- Moved away non-normative parts to "Discussion" and/or "Alternatives"
- Added `action=chat`
- Extended `via=` applicability to non-roomid cases to compensate
dropping the authority part semantics.
- Added a reference algorithm to parse a URI.
- Closed outstanding questions/discussion points.
- Added more cases for future evolution.
- Added "minimal syntax" options to the discussion of possible
alternatives
