    If the document's schema is an XML DTD, the method

org.w3c.dom.Element.getSchemaTypeInfo()

returns null, but an instance of TypeInfo is expected.

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

"If the document's schema is an XML DTD [XML 1.0], the values
are computed as follows:

- ...
- If this type is referenced from an Element node, the
  typeNamespace and typeName are null."

This implies that TypeInfo of the Element node is not null.

This bug affects new tests in JCK 1.5 (not integrated yet)
   api/org_w3c/dom/TypeInfo/index.html#TypeInfo[GetTypeNamespace002]
   api/org_w3c/dom/TypeInfo/index.html#TypeInfo[GetTypeName003]

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

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

class test {
    public static void main(String[] args) throws Exception {
        Document document = DocumentBuilderFactory
            .newInstance().newDocumentBuilder().parse("test.xml");

        if(document.getDocumentElement().getSchemaTypeInfo() == null) {
            System.out.println("getSchemaTypeInfo returns null");
        } else {
            System.out.println("OK");
        }
    }
}
----------------------------------------------------

------------------------------------------- test.xml
<?xml version='1.0'?>
<!DOCTYPE root [
    ELEMENT root (#PCDATA)
]>
<root>xxx</root>
----------------------------------------------------

------------------------------------------------ log
$javac test.java && java -cp . -showversion test
java version "1.5.0-beta"
