Hi,
the proposed Controlled Vocabulary (CV) can be defined in different ways. To include all different domains into it and have it administered within the CF standards might be a lot of work.
On the other hand one can think of a definition that allows for ontologies of different domains to be referenced. In this case only a limited CV needs to be supported by CF itself.
Cheers, ... frank
