The client requested to know whether the operating system that hosts the CA is an advanced server. If the CA implements the Config_SKU data, then it MUST inspect its value: If the value is Advanced_SKU, the CA MUST return 1; if the value is Standard_SKU or if the data is not implemented, the CA MUST return 0.
The CA MUST return this information through the fAdvancedServer field of a CAINFO (section 2.2.2.4) structure. The CA MUST return the CAINFO (section 2.2.2.4) structure through a CERTTRANSBLOB (section 2.2.2.2) structure.
Marshaling rules for the CERTTRANSBLOB (section 2.2.2.2) structure are specified in section 2.2.2.2.
