Really?
http://www.w3.org/TR/vocab-dcat/#vocabulary-specification

for example, lists all the properties used, most of which are dcterms...

I think it's useful to show how you expect terms from other vocabs to be 
used. If you want to add a domain and range, then, OK, as has been said 
- define sub properties, but you can do it less formally by adding a 
usage note (vann:usageNote). That can be free text that says "when used 
in this context, ex:foo is used in this way" Again, DCAT provides 
examples of this.

Hmmm...
