Is it possible to add a custom mechanism to pkcs11j?

[tstiemerling]

Hi I want to use pkcs11j with an HSM which has pre PKCS11 2.40 mechanisms, in particuler AES_WRAP and AES_WRAP_PAD are using:

#define CKM_AES_KEY_WRAP 0x00001090
#define CKM_AES_KEY_WRAP_PAD 0x00001091

and in pkcs11j we see:

#define CKM_AES_KEY_WRAP 0x00002109UL /* WAS: 0x00001090 /
#define CKM_AES_KEY_WRAP_PAD 0x0000210AUL / WAS: 0x00001091 */

I would like to know if I can add a custom mechanism to pkcs11j which would use the older numbers, and if so how we can go about doing that?
