Yes. Again, the 8 hex number is a de facto standard ;)

Actually not. "de facto standard" means that something is a standard because it's widely accepted or used, and not enforced by law or a FTS document in this case.

No.

The executive summary: MSGID is not required, but when used the ID must be unique.
