This class contains the input and output data resulting from invoking an IExternalResourceServer's LoadResource method.

After the call to LoadResource, the resulting ExternalResourceLoadData will be passed into IExternalResourceServer.HandleLoadResourceResults() so that appropriate UI can be displayed.

Server providers can inspect the ExternalResourceLoadData to get an ExternalResourceLoadContent object of the subclass appropriate to the external resource. The class also contains a copy of the ExternalResourceReference, and information about the context of the load operation.
