The payload type values in the examples are probably not allowed. In RTP
there are no PTs >127 - and all the dynamic ones are in the range
96-127. This applies to both examples in section 6.4. For the examples I
think you should restrict to 96-127 for RTP.
Also, a better term could be used instead of "payload type" (I think I
concure with Roni here), e.g "media format description" as used in
RFC4566 on page 24 together with the mid attribute. However, the label
attribute doesn't seem to be better than the mid attribute here, because
label attributes are (as far as I understood this) on the same level as
the mid attributes and apply to all media format descriptions (=payload
types) inside a media stream.
