An issue has been raised about inconsistencies in the RID syntax between
draft-ietf-mmusic-rid and draft-ietf-avtext-rid .

According to https://tools.ietf.org/html/draft-ietf-mmusic-rid-15 , we have:

rid-id = 1*(alpha-numeric / "-" / "_")


According to: https://tools.ietf.org/html/draft-ietf-avtext-rid-09#section-3
 :

As with all SDES items, RtpStreamId and RepairedRtpStreamId are
limited to a total of 255 octets in length. RtpStreamId and
RepairedStreamId are constrained to contain only alphanumeric
characters. For avoidance of doubt, the only allowed byte values for
these IDs are decimal 48 through 57, 65 through 90, and 97 through
122.
