DISCOVER_LITERALS Rowset
Returns information about literals, including data types and values, supported by the Microsoft XML for Analysis (XMLA) provider.
If you call the Discover method with the DISCOVER_LITERALS enumeration value in the RequestType element, the Discover method returns the DISCOVER_LITERALS rowset.
