Hello

Interpreting "token1=token2" as 'm-paramter' or 'accept-parameter' depends
on the m-type and sub-type fields. For your case I guess that they be
considered as 'accept-paramter' as no media is specified. 

True implmentation of Accept grammer causes ambiguity as grammer does not
differentiate between 'm-parameter' and 'accept-param' tokens. The most
appropriate interpretation will be context dependent as mentioned above.

Subject: [Sip-implementors] Issue with Accept grammar?


Hi all,

In the header,
Accept: */*;token1=token2;q=0.9

Should "token1=token2" be taken as accept-param or m-parameter?

Grammar is reproduced here for your convenience:

Accept         =  "Accept" HCOLON
                   [ accept-range *(COMMA accept-range) ]
accept-range   =  media-range *(SEMI accept-param)
media-range    =  ( "*/*"
                  / ( m-type SLASH "*" )
                  / ( m-type SLASH m-subtype )
                  ) *( SEMI m-parameter )
accept-param   =  ("q" EQUAL qvalue) / generic-param
qvalue         =  ( "0" [ "." 0*3DIGIT ] )
                  / ( "1" [ "." 0*3("0") ] )
generic-param  =  token [ EQUAL gen-value ]
gen-value      =  token / host / quoted-string

m-parameter      =  m-attribute EQUAL m-value
m-attribute      =  token
m-value          =  token / quoted-string

regards
Satya T
