I did not mean that, I meant that if *two* tags are added, that the
relation of these tags should not be interpreted other than indicated
by you. If two terms are added, one provider may intend a union,
another an intersection, another a specification of the first by the
second. I think we should make a recommendation that SPM is not meant
to allow this interpretation detail.
What you say is that one could introduce a new term "ecological
genetics" and then define it to be the intersection of ecology and
genetics, using OWL statements. I believe you can not define in OWL
how the repeated occurrence of a single attribute "Tag" with two
values shall be interpreted semantically, right?
