CRLs' cycle

[Pavel Krylov <Pavel.Krylov@xxxxxxxxxxxxxx>]

Hi all,
I didn't find any limitations for CRL infrastructure .. I found out
one interesting CRL configuration, when revokation only one certificate
in it follows to automatic revokation all certificates, those in
the cycle. Basically it seems like:

         CA1
          |
          V
        cert_1 -~-~-~-~-~-> crl_2
          |                   &
          |                   |
          |                   |
          V                   |
         crl_1 <-~-~-~-~-~- cert_2 <----- CA2


 -~-~-~ line shows who references to a crl.
 ------ line shows who issued a crl.

When no one certificate is revoked in the infrastructure, then
it looks good and works best ( I think ). But if only one certificate
is revoked by appropriate crl, then it follows to the automatic
revokation of another certificate ( in this example ).
So my question: is this infrastructure illicit by rfc2459 or not?
Another question: have I missed something?

Thanks a lot.
Pavel.
