Hi ACG
Have a look at the documentation here:
http://msdn.microsoft.com/en-us/library/ee633726(v=sql.110).aspx
This should answer all or most of your questions. Since the staging tables created by entity based staging are per-entity and these tables have a specific column per attribute I am not sure an example as elaborate as the one in that blog post is required.
I think you will find that entity based staging is a lot simpler to work with than the old staging functionality.
Let me know if you have more questions.
Regards
Arun
