Content item revision management, wiki markup.

No it isn't.

This is done too, isn't it?
It needs the option to roll back to a previous revision. Could be within a certain admin configured timeframe, such as 24 hours or 7 days or 10 years, whatever the specific customer's requirements are. For two reasons: some customers like to keep track of changes at any cost, and people make mistakes during the review and revise process and maybe deletes all the content (or an unhappy employer does it the last day at work) and a rollback is necessary. I don't know Wiki, though, so it might do just that.
