Ok. So, what does it imply then?

By your explanation, (using shorthand) it is *not* the case that T isA 
C, or J isA C. In practical terms, how would I say that T isA C, or J 
isA C in RDF? I *want* to have shared, inherited, attributes.

"tarod@softhome.net" says[1] I can get it by checking for inheritance 
explicitly using chained (prolog-like it seems) matching operators. 
However, you seem to say I shouldn't be doing this at all, using the 
above markup.

I don't wish to troll, but it would seem like inheriting of  attributes 
is a thing most people would expect to be able to do in RDF, somehow.
