An interesting point that hadn't come up beforex.  I certainly don't
want to depend on XML detail such as external entities, so it would
have to be expressed in terms of infoset infoitems, such as the
in-scope base URI.  

We've been considering the blank node identifiers to be scoped to the
RDF graph but I guess we either have in-scope base URI (baseURI
accessor of element event), or use the outermost XML document element
to pick from.
