I have re-read the latest incarnation just now. I am going to treat it as 
if I never read it before:


I know what a "shorter prefix than /64" is. A lot of readers might not, so 
I would like to insert at "(larger)" in there, or similar text.


Second paragraph, suggest text to clarify that adding the second PDP 
context is to achieve dual stack connectivity by means of these two PDP 


"restarts the ongoing applications". I don't like this wording, "will 
interrupt existing network connections" or similar text would be better.



"The purpose of the of the roaming profile is"


I don't understand the reference to 6052. Is this a referral to networks 
with NAT64 and/or 464XLAT? Then I think this should be clearer.

L_REC#4: Isn't this a duplication of one of the C_RECs?


I think this kind of document is valuable. Many operators do not have 
staff with right skill level to put in the requirements towards equipment 
manufacturers, and in some markets, the equipment manufacturers are 
selling directly to consumers without discussing details with operators. I 
also feel that the vendors of mobile equipment would benefit from having a 
more unified set of requirements from the operators.

Either these requirements can be gathered within the IETF for IP related 
matters, or operators can try to do it in another venue. I don't see why 
the IETF can't be the venue for this.
