Suresh: I apologize for not replying to your comments in a more timely manner with which they were originally sent. Despite this miss, Henning and I have reviewed and provided comments back which should make it in before publication. These changes are captured as comments from me, "[rsm]" and based on feedback (to me) from Henning, as "[hgs]".

Also will remove "(street addresses)".] [hgs: reworded it further, to make it less awkward, changed it as follows: OLD (*): Lo4. Validation ... for civic locations (street addresses). NEW: Lo4. Validation of civic locations: The mapping protocol MUST be able to report the results of validating civic locations. ] > > > > > >* Requirement Re6 > > > >Isn't this a requirement on the mapping server rather than > the protocol?

[rsm: see definition for "Location validation". Here, lack of validation doesn't necessarily imply that the location is not useful in routing, rather that, the fact that it may not have been checked (validated) beforehand is NOT reason enough to fail the call. No change made.] [hgs: No change made.] > > > > > >Minor > >===== > > > >* Requirement Re7 > > > >I am not sure what "common data structures and formats" > means. Does it > >mean commonly used data structures and formats? [rsm: Not really targeted at 'commonly used' data structures and formats as much as it is saying that 'standard' formats for location data, (e.g., a PIDF-LO). (Also, database structure would be beyond the scope of this doc, despite what the motivation text may imply to some.)] [hgs: Changed. OLD: "Re7. Common data structures and formats: The mapping protocol SHOULD support common formats for location data." NEW: "Re7. Common data structures and formats: The mapping protocol SHOULD support common formats (e.g., PIDF-LO) for location data." ] > > > > > >* Requirement Lo8 > > > >This perhaps needs to be a requirement on mapping clients, > servers and > >protocols and not just protocols [rsm: Despite some slight variances contained herein, this set of requirements is intended for the mapping protocol behaviour alone. No change made.] > > > > > >* Requirement Id1 > > > >Why does the mapping protocol need to distinguish between different > >emergency services? Isn't it the mapping service that needs > to be aware. [rsm: True enough. Therefore, the requirement has been reworded to clarify what it is that the protocol has to do.] [hgs: Changed as follows. OLD (*): MUST be able to distinguish between different emergency services, ... identifiers NEW: MUST be able to support different emergency services, distinguished by different service identifiers. ] > > > > > >* Requirements Id5, Id7, Id9 > > > >Not sure who this requirement is on.

[rsm: Id5, This is a difficult problem, since it really gets into some of the aspects being discussed around loose routing, etc.] [rsm: Id7, Agree that this is ambiguous, but have decided to leave it alone.] [hgs: I would leave it alone, given that this is AUTH48, not working group last call. They seem harmless, even if somewhat misplaced for a document titled "Requirement for Emergency Context Resolution".] [hgs: Id9, Changed. OLD: "Id9. Discovery of visited emergency numbers:" There MUST be a mechanism to allow the end device to learn visited emergency numbers." NEW: "Id9. Discovery of visited emergency numbers:" The mapping protocol MUST support a mechanism to allow the end device to learn visited emergency numbers." ] > > > > > >* Requirement Id6 > > > >I am not sure about the scope of this requirement.
