Typos in subpictures related text

[vdrugeon]

1. Typo in the semantics of subpics_present_flag: "subpics_present_flag equal to 1 indicates that subpicture parameters are present in the present in the SPS RBSP syntax. subpics_present_flag equal to 0 indicates that subpicture parameters are not present in the present in the SPS RBSP syntax.": "in the present" seems unecessary in both sentences.

2. In the SPS syntax, after signalling subpics_present_flag, sps_num_subpics_minus1 is directly signalled without a "if( subpics_present_flag )" condition. Is that intended? If it is intended, the number of closing '}' as well as the indentation of the syntax should be checked.

3. The syntax of the subpicture level information SEI message uses a syntax element num_subpics_minus1 that does not exist. Should it be sps_num_subpics_minus1 instead? In the semantics of the subpicture level information SEI message, there is another syntax element that is used twice max_subpics_minus1 that does not exist and num_subpics_minus1 is also used once. Should these three instances also be replaced by sps_num_subpics_minus1 ? The variable NumSubPics is also used, but never derived. Should it be replaced by sps_num_subpics_minus1+1?

All good catches, and your guesses are all correct. Fixed in JVET-P2001-v10.
