JVET-R0191 AHG9: On miscellaneous updates for HLS signalling [Hendry, S. Paluri, S. Kim (LGE)]
Item 5 of this contribution belongs to this category.
This proposes to specify a general constraint flag on LMCS i.e., no_lmcs_constraint_flag.
This is also proposed in JVET-R0286 aspect 2. See the notes for that contribution.

Item 4 of this contribution belongs to this category.
It is proposed to constrain that when sps_virtual_boundaries_enabled_flag is equal to 1 and sps_virtual_boundaries_present_flag is equal to 0, there shall be at least one picture header in the CLVS with ph_virtual_boundaries_present_flag equal to 1.
It was remarked that this constraint seems unnecessary and might interfere with potential extraction or splicing cases or encoder choices or low-delay operation cases, so no action was taken on this.
