If as we discussed on the call yesterday cannonicalID becomes Subject   
as in "the subject of the XRD" then we should consider having  
SubjectType at the XRD level.

If the XRD is about the subject the type is really making a assertion  
about that subject.

If the value of SubjrctType is  "Person" then I am saying that the  
subject is an identifier for a person not a service etc.

I think this also works if the Subject is not explicitly stated in the  
XRD.
