Possible that there are multiple matches, but unlikely :) In that case I
just need any one of them.
InfModel is only used for this case. I don't see how I can avoid it. If say
I want to find an instance of foaf:Document or its subclasses, just looking
at the raw model such as
:instance a my:Class .
is not enough, because it doesn't know whether my:Class is a subclass of
foaf:Document or not, without adding schema. That is why I'm using InfModel.
