Now . . . silly question, here, but it's been bugging me for a while, so:

Why can't the XRD file simply *contain*, in some (optional) 
element(s), the very information that would normally be documented in 
whatever page it was pointing at with the Subject field? In other 
words, if it is (implicitly) its *own* Subject, what (other than more 
bandwidth usage) can result in embedding the rules it will abide by?

I'm overstepping my understanding of XR* here, though, and 
speculating on what Subject is there for.
