[Atoca] Language and Media Type

[Hannes Tschofenig <[e-mail]>]

Hi all, 

Keeping Li (if the meeting minutes reflect his name correctly) noticed that we had a language requirement in the requirements draft but provided no corresponding solution in the SIP-CAP document. 

For subscriptions we currently have the following requirements:

---------------------

   Req-S1:

      The protocol solution MUST allow a potential Recipient to indicate
      the language used by alert messages.

   Req-S2:

      The protocol solution MUST allow a potential Recipient to express
      the geographical area it wants to receive alerts about.

   Req-S3:

      The protocol solution MUST allow a potential Recipient to indicate
      preferences about the type of alerts it wants to receive.

   Req-S4:

      The protocol solution MUST allow a potential Recipient to express
      preference for certain media types.  The support for different
      media types depends on the content of the warning message but also
      impacts the communication protocol.  This functionality is, for
      example, useful for hearing and vision impaired persons.

---------------------

No doubts have been raised about the usefulness of requirement S2 and S3 but with the requirements S1 and S4 it is not quite the same. 
Do we expect that a system will allow a subscriber to indicate language preferences and the ability to receive certain media types? 
Are there other parameters that would be more useful? 

Ciao
