There is already code to round-trip XUI files through the param block mechanism such that invalid attributes and default values are dropped and formatting is normalized. That code hasn't been exercised in a few years, though, so it probably won't run correctly right away, but it does provide a mechanism for keeping XUI files in line with changing param block schema going forward.
