I realise it is extremely late to comment on this but if there is time to make changes, could I suggest that the section on Traffic Shaping and Delivery Timing is removed (and the reference to it at the end of 8.1)?

The intention of SMPTE ST 2110-21 was not that payload definitions would reference it but that implementations could state that they comply with it.  For example, an implementation could say it uses the JPEG-XS payload as specified in RFC xxxx and compiles with SMPTE ST 2110-21.
Repeating provisions of ST 2110-21 such as the TP parameter is unhelpful because it could lead to a conflict if the parameters in the SMPTE standard are revised.

Thanks,
John Fletcher
