Hi Ben,

I agree. It seems that in general, @instanceof takes as its subject
the 'current' object, and if there isn't one, one is created (as a
bnode). This means that:
<div instanceof="foaf:Person">
...
</div>
doesn't make a statement about the document, but about a bnode on the
<div>. This neatly gives you what you and others on the list wanted
before, the ability to create typed bnodes without having to do lots
of mark-up.
Working 'upwards', it also means that mark-up like this falls out quite nicely:
<div rel="foaf:knows" instanceof="foaf:Person">
...
</div>
to mean that there is a relationship of 'foaf:knows' between the
nearest ancestor subject, and the bnode, which is itself of type
'foaf:Person'.
...all of which I think we've said before...I'm writing it down as
much for my own benefit as anyone else's. :)
Regards,
Mark
