In that case, is this possible?

   <ex:editor rdf:nodeID="abc">
     <ex:homePage rdf:resource="http://purl.org/net/dajobe/"/>

What about this?

   <ex:editor rdf:nodeID="abc" ex:fullName="Dave Beckett"/>

If rdf:nodeID is just a placeholder in a graph (and can be a subject, 
object, or both at the same time), both of these examples should be 
valid. If rdf:nodeID can only represent one or the other at a time 
(analogous to rdf:about for the subject and rdf:resource for the 
object), then they serve two separate purposes and should be named 

(I haven't checked the productions yet to see if the above examples are 
valid or not.)
