Notes
-----
The boundary between the "PT=SR or RR" and the "length" fields is wrong: The boundary is shown as being between bits 16 and 17; it should be between bits 15 and 16.  I.e., the "PT=SR or RR" field should be 8 bits long, not 9.

This is just a minor bug, because the equivalent diagram in RFC 3550 (the normative reference for RTCP) is correct.  Nonetheless, this bug should probably be added to the errata for RFC 3711
