This mechanism is of no value unless there are requirements for checking the integrity of encrypted data. The specification must provide mechanisms to check the integrity of decrypted data. Mandatory to implement algorithms should include integrity check mechanisms.
Integrity is a critical service.
There are a variety of attacks possible if the veracity of decrypted information is not validated. This validity check should be mandatory. Digital signatures provide integrity and could be used within an EncryptedData element. This is overkill. The specification may provide means to validate that a sequence of EncryptedData blocks have not been modified.
