Cannot use JDO 2 xsd for XML validation
---------------------------------------

                 Key: JDO-472
                 URL: https://issues.apache.org/jira/browse/JDO-472
             Project: JDO
          Issue Type: Bug
    Affects Versions: JDO 2 final
            Reporter: Ilan Kirsh
             Fix For: JDO 2 final


I am trying to use the last JDO 2.0 xsd with:

SchemaFactory factory = 
SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
URL xsdURL = getClass().getResource("/jdo_2.0.xsd");
Schema schema = factory.newSchema(xsdURL);

First I got the following exception (from newSchema):

org.xml.sax.SAXParseException: cos-nonambig: 
"http://java.sun.com/xml/ns/jdo/jdo":extension and 
"http://java.sun.com/xml/ns/jdo/jdo":extension (or elements from their 
substitution group) violate "Unique Particle Attribution". During validation 
against this schema, ambiguity would be created for those two particles.

And after trying to fix it, I got the following exception (from newSchema):

org.xml.sax.SAXParseException: src-resolve.4.2: Error resolving component 
'xs:attlist.jdo'. It was detected that 'xs:attlist.jdo' is in namespace 
'http://www.w3.org/2001/XMLSchema', but components from this namespace are not 
referenceable from schema document 'file:/D:/odb/dv/rt/class/jdo.xsd'. If this 
is the incorrect namespace, perhaps the prefix of 'xs:attlist.jdo' needs to be 
changed. If this is the correct namespace, then an appropriate 'import' tag 
should be added to 'file:/D:/odb/dv/rt/class/jdo.xsd'.

The same 3 lines work well with JPA 1.0 xsd. Has anyone used JDO 2.0 xsd 
successfully already?
