883	restriction for nesting_num_subpics_minus1 should be modified	LIJINGYA		"In current, restriction for nesting_num_subpics_minus1 is as below:
'''nesting_num_subpics_minus1''' plus 1 specifies the number of subpictures to which the scalable-nested SEI messages apply. The value of nesting_num_subpics_minus1 shall be in the range of 0 to 254, inclusive.

The restriction on 254 should be removed. There is any reason for this restriction. It was probably copied from the previous existing text for num_subpics_minus1 and is not relevant anymore, especially since nesting_num_subpics_minus1 is coded with ue(v) and not u(8) as num_subpics_minus1 used to be coded in (now it also uses ue(v)).

The constraint should be the following: “When present, the value of nesting_num_subpics_minus1 shall be less than or equal to the value of sps_num_subpics_minus1 in the SPS referred to by the pictures in the CLVS.”
