1. A method implemented by a decoder, the method comprising:
receiving a bitstream comprising a luma mapping with chroma scaling (LMCS) adaptation parameter set (APS) including LMCS parameters associated with a coded slice;
obtaining LMCS parameters from the LMCS APS associated with the coded slice; and
decoding the coded slice using the LMCS parameters from the LMCS APS,
wherein the bitstream further comprises an adaptive loop filter (ALF) APS containing ALF parameters,
wherein each APS includes an APS identifier (ID) selected from a predefined range,
wherein the predefined range is determined based on a parameter type of each APS, and
wherein APSs of a particular type share the same value space for the APS IDs and different types of APSs use different value spaces of the APS IDs.
