"Key Management Extensions for Session Description Protocol (SDP) and Real Time Streaming Protocol (RTSP)".

--------------------------------------
Type: Technical
Reported by: Riccardo Bernardini <[email-masked]>

Section: 3.2

Original Text
-------------
key-mgmt-spec = "prot" "=" KMPID ";" ["uri" "=" %22 URI %22 ";"] 

Corrected Text
--------------
key-mgmt-spec = "prot" "=" KMPID ";" ["uri" "=" %22 URI %22 ";"] ["data" "=" %22 base64 %22 ";"]

Notes
-----
There is an inconsistency between the ABNF for key-mgmt-spec on page 6 and the two SETUP examples on top of page 21.  In both examples a field data="..." is present in the keymgmt header, but the ABNF on page 6 does not allow for it.  The suggested correction solves the inconsistency.
