* If there is no critical extension, an empty list is returned.
*
* PARAMETERS
* "extension"

* "pOidsList"
* Address where the list of OIDs is returned. Must be non-NULL.
* THREAD SAFETY:
* Thread Safe (see Thread Safety Definitions in Programmer's Guide)
* RETURNS:
* Returns NULL if the function succeeds.
* Returns a CRL Error if the function fails in a non-fatal way.
* Returns a Fatal Error if the function fails in an unrecoverable way.
