Great. I haven't looked at your code yet, but did you implement a JSR 105 
provider using GenXDM? When we designed the JSR 105 API, one of our goals was to 
design it so that non-DOM implementations could be plugged in. I would be 
curious as to your experience with that and how well the API fit your needs.
