Note about dct:Standard and more:

The DC terms definition of dct:Standard was NOT changed, precisely
because it would have narrowed the definition and rendered some current
data invalid.

But more significantly, DC is moving toward the use of defining domains
and ranges of DC terms as being the semantic equivalent of schema.org's
"domainIncludes" "rangeIncludes". This is in recognition of the reality
that many uses of DC terms are working with legacy data that predates
the use of IRIs. Domains and ranges thus become recommendations or best
practices, but are not constraints.

Yes, I'll add this as a section (or paragraph) on constraint languages.
I assume (at the moment) that constraint LANGUAGEs are optional and
potentially outside of the application profile itself, but represent a
direction that APs should be moving toward, either as the AP language or
as a separate representation of AP-defined constraints.
