A user should be able to revert to the previous version of a Schema via the usual undo, restore, or rollback actions.
GIVEN a change has been made on a Shex
AND the user is allowed to make changes
THEN they can select the desired version
AND see the shape expression was reverted to that version

Restore, revert and undo (three different operations!) need to work like they do for Items.
To get some more details I tested on https://test.wikidata.org/w/index.php?title=Q177525
For UNDO:
In the history of an item there is an undo link
Clicking it takes you to a diff page (nicely formatted with a section for "description")
There is a summary box which will apparently be appended to the automatic summary
There is a publish changes button
Clicking this takes you to the view entity page
The page history now shows a new entry with (Undo revision 424509 by 10.68.16.199 (talk))
This edit entry is also tagged with Tag: Undo
Trying to undo the same edit again results in:
1 change cannot be undone because the value has changed in the meantime. There is nothing that can be undone here.
Trying to undo the undo takes us back to where we started
For restore:
The restore link in the item history take you to a diff page (nicely formatted)
There is a publish changes button
This takes you back to the view item page
message in history looks like: Restore revision 424510 by 10.68.16.199
Note: rollback works out of the box (example); undo requires special work because by default it sends you to an edit page (Wikibase only shows you a diff, with no ability to edit); restore is a Wikibase-specific feature (for normal Wikitext pages you edit an old revision and save that).
