If it is not dereferable to an appropriate RDF, the agent won't be able to
handle the information.  But if they intends to make the agent to be able to
do so.  They will.  That is my point!

What I can say. http://foo.com/bar#a and http://foo.com/bar#b is completely
two different resoruces.  Just as rdfs:subPropertyOf is completely different
from rdfs:subClassOf.  

Whether a #fragment identifier is dererencible is DEPENDENT on its base URI.
By your logic, http://foo.com/bar is less dereferenable than
http://foo.com/bar#abc? Isn't it an absurd assertion?  

Let's stop this, it once again stray away from the original topic.
