Thanks @maxl2287

Few comments - mot of them related to the PR361 of commonalities (which is not yet merged but hope soon to be):

• 429 is not required for GET & DELETE (as described here).
• It probably misses an example for 401: AUTHENTICATION_REQUIRED - look the PR361
• For 422 we have to align the code value with the PR361 also - like IDENTIFIER_MISMATCH instead of DEVICE_IDENTIFIERS_MISMATCH, SERVICE_NOT_APPLICABLE instead of DEVICE_NOT_APPLICABLE
• I guess the 422 UNNECESSARY_IDENTIFIER, MISSING_IDENTIFIER & UNSUPPORTED_IDENTIFIER examples must be added.
