Comparing AXUIElementRefs? AXUIElementCopyElementAtPosition(systemWide)

I need to know if the AXUIElement at x,y is the same element it was last time I asked, but AXUIElementRef is an opaque structure and every time I make a call AXUIElementCopyElementAtPosition (systemWide...), all other things being the same, I get a different AXUIElementRef back. I'm not convinced I have any way to accomplish this. I could compare certain attribute values, but the element may have moved, so the position and size may have changed. AXValues change all the time.

Is there a CFComparatorFunction or some kind of reliable GUID I can get from these guys?
