The spec doesn't define which one is chosen, sorting is only specified
for specificity (x/y > x/* > */*) and q value.
S.B. So would it not make sense to take an original order of Accept header values into consideration when all the media types
(those in Accept and Produces) have the same( or default 1.0 quality factor) ? It will make example 2/4 above work as intuitively
expected, without users having to add quality factors to Accept ?

The sorting for selecting a method in 3.7.2 step 3 applies regardless
of whether the @Produce/_at_Consumes is singular or multiple valued.
S.B. - but this sorting applies to @Produce/_at_Consumes values available on different matching methods
The sorting to select a type in 3.8 only applies when the chosen method
can produce more than one media type.
S.B. This applies to the intersection of Accept and a given @Produces' values (3.8.5, 3.8.7) ?
I guess the answer to my (subject) question is that the spec does not require Accept values be sorted
Thanks, Sergey
Marc.
