To publish as informational under the current IANA registration procedures would mean that the solution would need to be downgraded to a P-header, and the option tag would need to be removed. The option tag is there to meet one of the ISDN interworking requirements, as it is possible to say in DSS1 that the call should only proceed in the UUI is understood - i.e. interworking capability will be lost.
Is the requirement that the call should only proceed if the overall UUI transport mechanism is understood? Or only if the particular UUI type is understood? (I got the impression from earlier discussion in this thread that each of those types has an independent usage.)
If its important that the particular type be understood, then one option tag doesn't seem sufficient to get the desired effect.
