Circular references in RDF data model

Hello all,

A quick question abou the RDF data model:

I can't see any prohibition in the RDF Specification on circular
references in RDF triples (such that the subject and object are the same
resource).  Is this correct? It looks like a pitfall for implementors (a
likely cause of infinite loop bugs), but perhaps I've missed something?

Regards,

David.
