Review the concept of how annotations can impact validation

[Relequestual]

I'm wondering if the entire concept of annotations should be revised to something different - @karenetheridge

This is the direction I'd like to go. - @jdesrosiers

I'm happy to do that, too, but not in a patch to this version of the spec. Let's open a new issue to discuss that for the next one. - @gregsdennis

This may be best discussed in a GH Discussion. One should be created.

I believe that the annotation/assertion interaction aspects were covered by issue #1172 and PR #1203, and the rest is handled by discussion #204.
