RE: [reSIProcate] Smarter accept header validation in dum?


After thinking about this some more - I think I will just leave the API's as
is for now.  

If a UA supports a particular Content-Encoding or Language for one request,
there is no reason that it should not support it for other requests.  I
agree it would add flexibility, but it would also make it more difficult to
configure - ie. you would have to set the supported language / content
encoding for every request.  So unless there is strong opposition to this -
I won't bother changing the current api's for supported Content-Encoding and
Content-Language at this time.

Thanks,

Scott

Looks good, thanks.

As for the Content-Encoding and Content-Language validation, I think they 
should be request specific too.  It seems a bit odd to me why anyone who 
spoke two languages would for example want to only accept one for Message
and 
the other for Invite, but it should be perfectly valid.  I can't imagine a 
huge need for this functionality, but at the very least changing the current

behaviour would keep the api consistent with the new mime type validation.

~Scott
