How to assign dynamic value to an xml attribute in a resource tag?

Question

I have a very simple demo project in here. In my code I need an xml resource. In the xml resource I need to set the attribute value to be a dynamic value such as read from configuration file ect... I tried binding but it seems like all text binding syntax are passed to the attribute.

So, how can we bind/or work-around to have value set in resource tags be dynamic?

Hope to hear from all of you. Nam.
