Title: Remove contradictory wording.

The prose here was outright contradictory ("**must** support" followed by "may omit support").

This was probably hit because of the change of **should** to **must** through the document, combined with the redundant original wording.

I also removed the parenthetical remark because it has no place in this document now.
