    If an element is declared using anonymous simple type, its type info name is null,
i.e. the method TypeInfo.getTypeName() returns null.

The documentation of the interface org.w3c.dom.TypeInfo reads:

"If the document's schema is an XML Schema [XML Schema Part 1] , the values are computed
as follows using the post-schema-validation infoset contributions (also called
PSVI contributions):
...
  If the [validity] property exists and is "valid":
  1. ...
  2. ...
  3. ...
  4. If the [type definition anonymous] exists:
      1. ...
      2. Otherwise, expose the namespace and local name of the corresponding anonymous
         type name. "

This implies that the name of the TypeInfo is not null and not empty.

This bug affects new test in JCK 1.5 (not integrated yet)
   api/org_w3c/dom/TypeInfo/index.html#TypeInfo[GetTypeName008]

The bug is found in jdk1.5.0/beta/b30.

To reproduce the bug place test.java, test.xsd and test.xml to your current
directory, then compile and run test.java as shown in the log below:
------------------------------------------ test.java
import org.w3c.dom.Document;
import org.w3c.dom.TypeInfo;
import javax.xml.XMLConstants;
import javax.xml.parsers.DocumentBuilderFactory;

class test {
    static final String SCHEMA_LANGUAGE = "http://java.sun.com/xml/jaxp/properties/schemaLanguage";
    static final String SCHEMA_SOURCE = "http://java.sun.com/xml/jaxp/properties/schemaSource";

    public static void main(String[] args) throws Exception {

        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        dbf.setNamespaceAware(true);
        dbf.setValidating(true);
        dbf.setAttribute(SCHEMA_LANGUAGE, XMLConstants.W3C_XML_SCHEMA_NS_URI);
        dbf.setAttribute(SCHEMA_SOURCE, "test.xsd");

        Document document = dbf.newDocumentBuilder().parse("test.xml");

        TypeInfo type = document.getDocumentElement().getSchemaTypeInfo();

        String typeName = type.getTypeName();

        if (typeName == null) {
            System.out.println("returned typeName is null");
        } else if (typeName.length() == 0) {
            System.out.println("returned typeName is empty");
        } else {
            System.out.println("OK");
        }
    }
}
