[Slim] Allowing multiple values in an answer

[Randall Gellens <[e-mail]>]

The second of the two remaining open questions is if we should allow 
an answer to contain multiple values.  I do not think this is the 
intent of the text that has been in the draft for some time; 
regardless, we could make such a change, but I question if we can do 
so now, when we've essentially passed IESG review.

I edited a version of the draft that contains all remaining 
clarifying editorial changes to also make this technical change and 
attached is a diff showing what it would look like.  However, I think 
we should not make the change since it could introduce additional 
complexities or problems that we aren't considering.  I think we 
could make such a change in a future extension or revision.  I don't 
think we'd have an interoperability problem since endpoints 
conformant with the more restrictive version will not generate such 
answers, and would regard regard receiving such answers as an error, 
but not one that would fail a call.
