Section A.4.3 says:

|  In SRTP, a cryptographic context is defined as the SSRC, destination
|  network address, and destination transport port number.  Whereas RTP,
|  a flow is defined as the destination network address and destination
   transport port number.  This results in a problem -- how to
   communicate the SSRC so that the SSRC can be used for the
   cryptographic context.

It should say:

|  In SRTP, a cryptographic context is defined by the SSRC, destination
|  network address, and destination transport port number, whereas in RTP,
|  a flow is defined by the destination network address and destination
   transport port number.  This results in a problem -- how to
   communicate the SSRC so that the SSRC can be used for the
   cryptographic context.
