Specify any `flags-map` restrictions

[steven-bellock]

Issue raised by @mcr.

Are there any restrictions on combinations of the flags-map booleans? Or are they all completely independent of one another?

CoRIM Authors discussed this in CoRIM Meeting 16th Jan 2026, that the document cannot and shall not mandate specific settings of Flags and their restrictions of inter-operability. It is for the Endorser to define this.

Verifier would simply compare what is present in the Evidence and then what is provided in the Reference Value

Note: while addressing this, let's add a non-empty wrapper around the map.
