Claim 0:
1. A method of processing video data, comprising:
performing a conversion between a current picture of a video and a bitstream of the video according to a rule,
wherein the rule specifies that a first syntax element specifying whether reference picture resampling is enabled is included in a sequence parameter set of the bitstream, and a second syntax element specifying whether a spatial resolution of a picture is allowed to change within a coded layer video sequence (CLVS) referring to the sequence parameter set is conditionally included in the sequence parameter set,
wherein the second syntax element is included in the sequence parameter set in a case that the first syntax element specifies that the reference picture resampling is enabled, and
wherein, in a case where the second syntax element is not included in the sequence parameter set, the second syntax element is inferred to be equivalent to a value indicating that the spatial resolution of the picture is disallowed to change within the CLVS.
