David, I'll keep this reply quite short, as I have just returned from two days worth of skiing (yes, even committers need some days off, to everybody else's suprise ... ;-)). There's been a comment on one of the existing Jira XML issues mentioning that apparently (some) pull parser now supports the SAX API.
Having said that, I am not sure whether this is valid, and even if so, how integration would look like. More on this tomorrow ...
