Hi Eugene,

All I can say is that you are not catching up on your weekend emails but on 
last two years worth of discussions in EAP WG :)) on the draft. It is difficult 
 for me to understand why IESG has these rules that practically reset 
everything that has happened with the draft since it got introduced long time 
back and require authors to satisfy everyone again from the very beginning on  
fundamental questions that were dealt with longtime back and are hard to 
explain/resolve/convey over emails...................

A very brief response (which I am sure can not staisfy you and obviously can 
not because discussion on this topic is something that has always taken a long 
time to converge) is, the draft does not mandate anything on  the part of the 
service provider. It is about ABNF. The information on roaming partners is just 
a hint for the client device about hotspot operators own roaming partners, and 
no where does it say it has to be an exhaustive list of all of its roaming 
partners roaming partners partner etc..IT is not tryin g to solve world hunger 
problem.  The service provider, can also choose not to advertise any of its 
partners, a couple of them or all of them if there are a handful. This draft is 
NOT trying to address your  thousands of roaming coprorate partners scenarios 
but is to be used by 3GPP SPs. Again this roaming partner information is just a 
hint and I am not sure why people expect this draft to solve everyone's roaming 
issues and problems with all the scalability to handle n possible mediating 
partners etc. ...... to be honest I am not sure if some one can design such a 
solution that satisfies everyone's roaming dreams.


BR,

Farooq
