It would also be good to add text to this effect:

"""New properties can be defined by other specifications using the  
extensibility mechanisms described in Section 6. Such properties SHOULD  
identify the components they are relevant to, and their names SHOULD  
NOT conflict with those of already-defined properties."""

(I'm a little worried about name space management of properties; has  
there any been any discussion of this?)
