The details of SDP for H.264 are in RFC 6184 section 8, of course.

But if a device does not parse the max-fs parameter (for example), that
seems to be to be correct -- it simply does not support a higher frame
rate than is specified in the profile.  So the device's response would
(I think) not include a max-fs, and the result of the negotiation would
be that only the profile frame rate is to be used.
