As with the SST headers, I think "Supported" and "Require" are headers for 
which the semantics touch the role of the intermediate (sems) and thus should 
be properly set - e.g. if on one side timer is required, it doesn't necessarily 
need to be required on the other side, and it also should be Supported on both 
sides. So even if that specific interop problem is related to a bug in *, I 
would say that Supported/Require handling for relayed requests should be 
improved in sems' B2B.
