1. A method for decoding comprising:
obtaining video data representative of a video sequence;
obtaining a first syntax element from the video data indicating with a first value that a presence of a container of type adaptation parameter set is allowed and with a second value that a presence of a container of type adaptation parameter set is not allowed;
checking a value of a first sequence parameter set level syntax element indicating an activation or a deactivation of a luma mapping and chroma scaling (LMCS) mode, the LMCS mode using at least one coding parameter provided by a container of type adaptation parameter set; and
outputting an information representative of a nonconformance of the video data responsive to the first syntax element indicating that a presence of a container of type adaptation parameter set is not allowed and the value of the first sequence parameter set level syntax element indicating an activation of the LMCS mode for blocks of the video data.
