Bind xmlconnector to a normal variable?

I just started experimenting with the data binding capability in 2004 Pro, and have been working with the xml connector.

I got that pretty much figured out. I load up an xml and can display a node value in an textarea component. No real problem there.

But, what I want to do and can’t really figure out, is how to bind that same node to a regular ol’ flash variable. I found this note in one of macromedia’s demos, but there is no further explanation:

For each binding in the list, you need to set a UI component, a variable reference, or a literal value to pass to or from the web service.

Where can I do this? It would be great to just set the “bound to” target to something like _root.myVar

Any thoughts?
