One thing occurred to me that we may have forgotten about:

This draft introduces the dcsa attribute, which allows other attributes 
to be used in this new scope. It notes that not all attributes are 
suitable for use this way.

ISTM that in the future other attribute definitions should include an 
indication of whether they can be used with dcsa, and the IANA 
registration of the attribute ought to include this. And then there is a 
need to update the iana registry for all the existing attributes.

	Thanks,
	Paul
