I am not familiar with the term "IDP partitioning" (does IDP stands for
"Issuing Distribution Point"?).

The partitioning is not by reason codes, Every X certificates are
pointed to a certain CDP to reduce CRL's size, CRL's are separated by
the Issuing Distribution Point extension. 

I am sorry but I didn't quite understand from your answer if there is an
intention to support this in openssl future versions? (I know that I am
pushing it a little by if there is such a plan I would also like to know
approximately when it is planed to be done). 

Thanks a lot for your help.

Hagai.

By a "partitioned CRL" which extension is being used for the
partitioning? Is
it IDP partitioning by reason code?

If so this *may* be looked at at some point along with the X509_STORE
issues
you mention.
