I've modified the source I've download to include user data extensions I required. I did not remove the original user data facility.
I was wondering if anyone is interested in getting it checked in to the Xerces distribution. I will still need a while to thoroughly test it. Also on the agenda: I desparately need an implementation of Mutation Events and would like to code it for Xerces. Is there anyone interested this or anyone with advice on where to start or on the what not to do's of such a project. Thanks -John
