I've made a little XML->Object mapper using dom4j which can use whatever parser you like so that we're not hooked directly into xerces. A jakarta-turbine-stratum repository will be appearing shortly. It contains the mapper that I've been talking about on the commons list. > Note: gump's nightly nags are still based on Xerces 1 at the moment.
