No, I said that I want to name an attribute that consists of a group of
TLVs, not the same thing.  For example: a cryptosuite consists of a an
encryption algorithm identifier and an integrity-protection algorithm
identifier.  Multiple cryptosuite attributes can be in the same message.
Both the integrity-protection and encryption algorithms MUST be present or
the cryptosystem attribute is malformed.  I know how to do this easily & in
a way that comprehensible in Diameter or w/a legacy RADIUS attribute.
Apparently it is not possible to specify such a thing in an easily
comprehensible fashion using Extended Attributes.  I consider this to be a
problem (now -- I didn't before because I hadn't run into this,
short-sighted, I know); I'm not sure why (given your sympathetic concern for
programmers who would separate the word "hello" into 5 different attributes
;-) do not.
