you didn't answer those questions. You said that a mid-rad implementation
providing some hull() command that would give an enclosure would be
"conforming".

But on the other side, if the standard requires to implement *at least* one
inf-sup datatype then my understanding is that a package implementing only
mid-rad or (x, inf_err, sup_err) would be not conforming.

Thus iRRAM would not be conforming.

Am I correct?
