Hi Gilles,

Thanks for your reply! :-)

The CA also offers OCSP, which is obviously the preferred way to
validate certificate status. I am just trying to make sure that there
is support from the "applications world" to such a CRL partitioning
scheme. Wide interoperability is a key goal.

Regards,

Nuno Ponte
