xml:space causes validation error with catalogs

[Dazhi Jiao]

Hi,

I am using xerces-j 2.9.1 to parse some TEI (text encoding initiative)
xml.

I am using XML catalogs. The XSD are specified in the catalogs. (they
are setup correctly, I've tested it)

The parser can't parse the document because the following error:

Document is not valid.
Error (1408,36) : src-resolve: Cannot resolve the name 'xml:space' to
a(n) 'attribute declaration' component.
Error (1408,36) : s4s-elt-must-match.1: The content of
'att.xmlspace.attribute.xmlspace' must match (annotation?, ((attribute |
attributeGroup)*, anyAttribute?)). A problem was found starting at:
attribute.
Validated in -1 millisec.

The error actually is in the xsd:

Here is where the error happens in the xsd:

  <xs:attributeGroup name="att.xmlspace.attribute.xmlspace">
    <xs:attribute ref="xml:space"/>
  </xs:attributeGroup>

Here is where xml:space is defined (in an imported xml.xsd)

  <xs:attribute name="space">
    <xs:annotation>
      <xs:documentation>signals an intention that white space should be
      preserved by applications</xs:documentation>
    </xs:annotation>
    <xs:simpleType>
      <xs:restriction base="xs:token">
        <xs:enumeration value="default"/>
        <xs:enumeration value="preserve"/>
      </xs:restriction>
    </xs:simpleType>
  </xs:attribute>

Here are my code to parse the xml (the xsd are in the catalogs files)

                DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
                factory.setNamespaceAware(true);
                factory.setValidating(true);
                factory.setAttribute(

"http://java.sun.com/xml/jaxp/properties/schemaLanguage";,
                                "http://www.w3.org/2001/XMLSchema";);

                // Create catalog resolver and set a catalog list.
                XMLCatalogResolver resolver = new XMLCatalogResolver();
                resolver.setPreferPublic(true);
                resolver.setCatalogList(catalogs);
                factory.setAttribute(

"http://apache.org/xml/properties/internal/entity-resolver";,
                                resolver);

                DocumentBuilder builder = factory.newDocumentBuilder();
                ValidationReport report = new ValidationReport();
                builder.setErrorHandler(report);
                builder.setEntityResolver(resolver);
                builder.parse(xmlFile);

                return report;

I can't see what exactly is wrong with the xsd. Could someone help me
out?

Thanks!

Dazhi
