[SmartcardServices-Users] PIV.tokend question: on-card key escrowed support?

Does the OS X Forge provided PIV.tokend support the on-card key history specifications in NIST SP 800-73-3 Part 1? And if so, can OS X Applications [via the PIV Keychain] make use of the Key History -> Retired X.509 Certificate for Key objects Link to info http://csrc.nist.gov/publications/nistpubs/800-73-3/sp800-73-3_PART1_piv-car...
