Between components, I think you are actually passing a dataset object. Maybe .NET behind the scenes converts to XML, passes the data, and converts back to a dataset (which btw is cool if it really does this for you) but I have not seen anything that says this is the case.

Maybe it is the case...

This is a really good question!!
