The specification that each of the TokenD modules implement. I referenced
an API that exists but does not appear to be documented (at least publicly).

I brought these up as I am on a team maintaining a product with a TokenD
module for our smart card support and have run into stumbling blocks with
supporting the new operating systems with no reliable channel on changes
aside from poking and prodding behavior as best as I can when new beta
releases come out.

See man page for SmartCardServices….
Thanks for this - I'll keep an eye on man-page changes.
