ConstReadonlyWHEN_REQUIRED: "WHEN_REQUIRED"When set, checksum validation MUST NOT be performed on response payloads of operations UNLESS
the SDK supports the modeled checksum algorithms AND the user has set the requestValidationModeMember to ENABLED.
It is currently impossible to model an operation as requiring a response checksum,
but this setting leaves the door open for future updates.
ReadonlyWHEN_SUPPORTED: "WHEN_SUPPORTED"When set, checksum validation MUST be performed on all response payloads of operations
modeled with the httpChecksum trait where responseAlgorithms is modeled,
except when no modeled checksum algorithms are supported by an SDK.
httpChecksum
Determines when checksum validation will be performed on response payloads.
