The CollectionSchema method is received by the server in an RPC_REQUEST packet. If the specified IAppHostElement object supports child collection elements, the server returns the schema and constraints of the collection that is contained in the corresponding IAppHostElement object.

 [propget] HRESULT CollectionSchema(
   [out, retval] IAppHostCollectionSchema** ppCollectionSchema
 );

ppCollectionSchema: Contains an IAppHostCollectionSchema.

Return Values: The server MUST return zero if it successfully processes the message that is received from the client. In this case, *ppCollectionSchema 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.
