Title: Clarify canonical language process

Addresses #479.

Pulls the canonical statement language map requirements out of the table.

Replaces "should" and "will" with "MUST". I'm happy to replace lowercase "should" with "MUST" as we've said that descriptive language is still required to be followed.
