Again I support Richard's argument; I think that changing the
suggested range of dct:language to dct:LinguisticSystem would only
confuse the majority of potential adopters at this stage.

Furthermore, at this stage of he game I think any stakeholder
community that is creating apps which care whether the range of
dct:language is dct:LinguisticSystem is (arguably) sophisticated
enough to deal with any ambiguities that may arise if it isn't so
tightly constrained...

Shouldn’t DCAT inherit the (narrower) range as defined by DCMI?
