C2MS11 — Lack of Required Fields in Sub-elements

We have a number of cases where there is a listing of something, like Files in Product Message. Although Num-of-files is required, nothing in the file itself is required.

Should review these and decide if any of these are dependent, and therefore required for each File.

Note that this is true in many other cases, need to find them all and come up with a plan for each.

Defer to a later release

This is work that should be done in a future release.
