Thanks Francois,

This is something that needs to be updated in the current draft.

>>> The Proposed Resolution
>>> ===================
>>> Co-authors of the three I-Ds as well as WG chairs of the

>>> Please let us know if you have an issue/concern with this.
>>>
>>> o Regarding RPH-Priority:
>>> 	* tsvwg-emergency-rsvp will go ahead with its requests 
>to IANA to 
>>> provide numerical registry for RPH priority (via extending existing 
>>> RPH registry). See IANA Considerations section of tsvwg-

>>> 	* nsis-qspec (in section 6.2.10) will point to this 
>registry instead 
>>> of defining its own values
>>> 	* dime-qos-parameters (in section 4.11) will point to 
>this registry 
>>> instead of defining its own values
>>> 	* tsvwg-emergency-rsvp (in section 3.2) will keep 
>pointing to this 
>>> registry.
>>>
>>> o Regarding Admission Priority:
>>> 	* every protocol spec will only indicate that "higher 
>value means 
>>> higher priority".
>>> 	* there is no attempt to define what specific values 
>should be used 
>>> for what. this is left outside the scope of the protocol specs.
>>> 	* each protocol spec will add a statement clarifying 
>that a given 
>>> Admission Priority is to be encoded with the same value in each of 
>>> the three protocol spec. For example, in 
>tsvwg-emergency-rsvp, under 
>>> section 3.1.  we will add:
>>> "      A given Admission Priority is encoded in this information  
>>> element
>>> 	using the same value as when encoded in the Admission Priority
>>> 	parameter defined in section 6.2.9 of [nsis-qspec], or in the 
>>> Admission
>>> 	 Priority parameter defined in section 4.10 of [dime-qos- 
>>> parameters].
>>> 	In other words, a given value in any of the [emergency-rsvp] 
>>> Admission
>>> 	Priority information element, the [nsis-qspec] 
>Admission Priority 
>>> parameter
>>> 	or the [dime-qos-parameters] Admission Priority 
>parameter, refers to
>>> 	the same Admission Priority.
>>> "
>>> 	* the mirror statement will be added in nsis-qspec (section
