// ck1 Must be specified when object is created with C_CreateObject.

// CKR_TEMPLATE_INCONSISTENT. A set of attribute values is inconsistent if not
// all of its members can be satisfied simultaneously by the token, although each value
// individually is valid in Cryptoki. One example of an inconsistent template would be
// using a template which specifies two different values for the same attribute. Another
// example would be trying to create a secret key object with an attribute which is
// appropriate for various types of public keys or private keys, but not for secret keys.
// A final example would be a template with an attribute that violates some token
// specific requirement. Note that this final example of an inconsistent template is
// token-dependent—on a different token, such a template might not be inconsistent.
