// TODO: should request and response payloads implement validation?
// Sort of makes sense to run validation over the request at this level, at least for spec
// compliance, though perhaps handlers may want to be more relaxed with validation.
//
// Should the response object run through validation? What is a valid response may change as
// the spec changes. Maybe this should just be handled by spec compliance tests.
// 4.1
//
// This operation requests the server to generate a new symmetric key as a Managed Cryptographic Object.
// This operation is not used to create a Template object (see Register operation, Section 4.3).
//
// The request contains information about the type of object being created, and some of the attributes to be
// assigned to the object (e.g., Cryptographic Algorithm, Cryptographic Length, etc.). This information MAY be
// specified by the names of Template objects that already exist.
//
// The response contains the Unique Identifier of the created object. The server SHALL copy the Unique Identifier
// returned by this operation into the ID Placeholder variable.
// CreateRequestPayload 4.1 Table 163
//
// TemplateAttribute MUST include CryptographicAlgorithm (3.4) and CryptographicUsageMask (3.19).
