Writing a large-scale Pivot app, I have a use case for a common Resources class that holds things like OK, Cancel, etc. However, a WTKXSerializer is associated with only 1 Resources instance, so within my WTKX file, I cannot reference local resources and common resources. Thus, I'm forced to duplicate my common resources in each local Resources instance.
What would be nice is for Resources to have a parent Resources object (similar to ClassLoader) creating a resources hierarchy. Then I could put all my common resources in the root Resources, and have that be the parent of my local Resources instances.
