both OCSP and CRLs are signed, and this is enough for validation,
there is no need of SSL;
and an infinite recursion would be implied because of
the need of validating these SSL-certificates the same way
as the origin SSL-certificate ...

but be aware the CRLs can be in an LDAP - done by bad CAs;
OCSP must be HTTP
