Multi-Part Operations for XMSS and HSS #32
Description
As noted by Falko Strenzke in https://github.com/oasis-tcs/pkcs11/wiki/TC%E2%80%90Meeting%E2%80%90Minutes20250716
Only single-part operations are defined for XMSS and HSS
- This is worth addressing, but out of scope for editorial. Will consider for 3.3.
