Nope, you're the first.  Thanks.

Yes, you're right.  Thanks.

True.  Question for the list: should this actually be:

  key-s-tag   = %x73 [FWS] "=" [FWS] ( "*" / key-s-tag-type-list )

with key-s-tag-type-list defined as the colon separated list?  Put 
another way, should "*" be a special qualifier, or just another type 
in the list?
