Section page 64 says:

rtp(profile_value, ts_stride_value, time_stride_value,
    reorder_ratio_value)
{
  UNCOMPRESSED {
    ENFORCE((profile_value == PROFILE_RTP_0101) ||
            (profile_value == PROFILE_RTP_0107));
    rtp_version =:= uncompressed_value(2, 0) [  2 ];

It should say:

rtp(profile_value, ts_stride_value, time_stride_value,
    reorder_ratio_value)
{
  UNCOMPRESSED {
    ENFORCE((profile_value == PROFILE_RTP_0101) ||
            (profile_value == PROFILE_RTP_0107));
    rtp_version =:= uncompressed_value(2, 2) [  2 ];

Notes:

rtp_version is set to 2, not to zero.

See RTP Header Fields page 115 :

Version

This field is expected to have the value two and the field is
therefore classified as STATIC-KNOWN.
