http://nagoya.apache.org/bugzilla/show_bug.cgi?id=11326 Parser does not validate if entity resolver is used and XML does not define schemaLocation Summary: Parser does not validate if entity resolver is used and XML does not define schemaLocation Product: Xerces2-J Version: 2.0.2 Platform: PC OS/Version: Windows XP Status: NEW Severity: Blocker Priority: Other Component: SAX AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] We need to assign an entity resolver during parsing, in order to use local copies of schema/dtd's, therby, overidding what the user's document is dictating.
