3.2.1.4.3.2.2 PropID = 0x00000002 (CR_PROP_PRODUCTVERSION) "CA Product Version"

The client has requested the CA product version property. If the CA implements the Config_Product_Version datum, the CA constructs a [UNICODE] string of the form "w.x.y.z" or "w.x:y.z",<91> where w, x, y, and z MUST be numeric values indicating the version of the server hosting the CA, which might or might not match the version of the CA returned for the previous property. If the CA does not implement the Config_Product_Version datum, it MUST return a NULL string. The [UNICODE] string MUST be returned through the CERTTRANSBLOB (section 2.2.2.2) structure.<92>

Marshaling rules for CERTTRANSBLOB are specified in section 2.2.2.2.
