Legal issue with pkcs11 headers

Hi!

I was reviewing our package licensing and lib/isc/includes/pkcs11/pkcs*.h headers came to my eyes. Their license seems to be quite restrictive. Have you reviewed its license before adding it to bind 9.11? Do you believe it is compatible with Mozilla Public License used for sources? I am not lawyer, but it seems it might not be compatible.

As a coincidence, similar file from OpenJDK was discussed on Fedora Legal mailing list few days ago. Apparently it is the same file BIND also distributes.

I know you support Windows builds where such functionality is important. Do you have any reason why headers from p11-kit are not used instead?

Marking as private issue.
