However, in case of "Initiate Dynamic Capacity Release", no region-id is specified in the request payload. However, specification says that f "Initiate Dynamic Capacity Release" command fails with "Invalid Input" if invalid region-id is specified. Is this an errata ? This is true in both CXL3.0 and CXL3.1 (draft). Hi Shesha Please do not discuss consortium draft documents on public lists. Here we can only talk about those that are published. Also, these questions are probably better addressed within the CXL consortium (SSWG) anyway.
