The Schema method is received by the server in an RPC_REQUEST packet. In response, the server returns the schema and constraints of the specified property, as defined in the IAppHostPropertySchema object that is returned.

 [propget] HRESULT Schema(
   [out, retval] IAppHostPropertySchema** ppSchema
 );

ppSchema: Set with the IAppHostPropertySchema for the corresponding IAppHostProperty.

Return Values: The server MUST return zero if it successfully processes the message that is received from the client. In this case, *ppSchema is not NULL. If processing fails, the server MUST return a nonzero HRESULT code as defined in [MS-ERREF]. The following table describes the error conditions that MUST be handled and the corresponding error codes. A server MAY return additional implementation-specific error codes.
