0CRM_STDELV DataSource

Does anybody know the datasource for this infosource in CRM? If they do, can you let me know, but if possible could you tell me how you know (if there is something in the help text etc. I would rather look there first so that I don't have to keep posting questions in this forum!).

I have checked the help text but it does not provide the datasource.

Can anybody explain why these infosources would not have datasources assigned automatically during BC activation? I thought that I had an assigned datasource but perhaps I didn't. Could that be the problem?
