* add comments to setValidating re how to validate against an xml schema * remove method setPublicId; it was always broken * rename getPublicId --> getDtdPublicId, add getDtdSystemId * move code that sets up XMLReader callbacks into SAXHandler.initCallbacks so it is accessable to users who create XMLReaders directly.
