Yes, it can.  But should it?  (No, IMO.)

I think there will be standards where extensibility should not be designed 
in.  "Don't apply" might be one reason.  "Violates interoperability 
requirements" could be another.  There may be others.

IMO, Extensibility should remain a separate topic.  Certainly for 
FPWD.  But I haven't yet heard anything to convince me that we should put 
aside our original reasons for special attention to Extensibility.
