Using <oXygen/> XML Editor 11.2, build 2010080212. Load http://scap.nist.gov/use-case/cyberscope/cyberscope-auto-feed-example-20100723.xml. An explicit validation results in several Xerces errors in xAL.xsd and xNL.xsd. Is this due to actual errors in the schemata, or due to <oXygen/> validation settings? Regards, Gary
