Having vs:minVersion is not being honored by BaseX. Daniel Von: Hans-Juergen Rennau [mailto:hrennau@yahoo.de] Gesendet: Dienstag, 22. Januar 2019 15:15 An: BaseX Support Betreff: [basex-talk] XSD 1.1 - Element not found Dear BaseX team, trying to use XSD 1.1, I encounter a problem. As indicated in the documentation, I added to the lib folder the jar files from the newest Xerxes distribution (Xerces-J-bin.2.12.0-xml-schema-1.1.zip, download fromhttp://xerces.apache.org/mirrors.cgi#binary ). The problem: when using the schema attribute vc:minVersion="1.1", validation fails with the message: 1:41: cvc-elt.1.a: Cannot find the declaration of element 'Foo'. But the element is there, and the namespace matches the target namespace. When changing the attribute vc:minVersion="1.0", validation works, but, of course, cannot cope with 1.1 features. (The same applies to validation after removing the attribute.) I tried both - copying only the four jar files named in the documention, cupv10k-runtime.jar org.eclipse.wst.xml.xpath2.processor_1.2.0.jar xercesImpl.jar xml-apis.jar and then I tried copying all jars: cupv10k-runtime.jar icu4j.jar org.eclipse.wst.xml.xpath2.processor_1.2.0.jar resolver.jar serializer.jar xercesImpl.jar xercesSamples.jar xml-apis.jar Any suggestions would be welcome! With kind regards, Hans-Jürgen PS: I use Java version 1.8.0_181-b13
