BT/NT confusion in IVOAT

[Douglas Burke]

Rick,

I've just tried out the experimental SKOS validator [1] on your IVOA 
thesaurus and it spits out some problems [2].

       (this is only with the base level)

I remember you mentioning the Ae/Be/Herbig AeBe circularity before, but 
the other issues are new to me (most are of the form "term has same NT 
and RT", but there are a couple where the prefLabel field matches one of 
the altLabel fields)
