How to create a datasource which Connection type is SQL Server Anlysis Service in rss script?

I am making a rss script to deploy the reports and datasources.
I need to create a datasource which Connection type is SQL Server Anlysis Service. Thanks.

Does anyone know that? Or I am asking a stupid question?|||

I assume this has already been resolved but for anyone else;

Create a Datasouce in VS (or BIDS) of the Connection Type that you require and then open up the resulting .rds to

view the resulting connection type code.

i.e. For Analysis Services Connection Types

<Extension>OLEDB-MD</Extension> = Extension Code is "OLEDB-MD"
