Here is an overview of the issue:
---------------------------------------------------------------------
        Key: XERCESJ-929
    Summary: getElementById does not work
       Type: Bug

     Status: Closed
 Resolution: CANNOT REPRODUCE

    Project: Xerces2-J
 Components: 
             DOM
   Versions:
             2.6.2

   Assignee: 
   Reporter: Nils Kilden-Pedersen

Environment: Operating System: Windows NT/2K
Platform: PC

Description:
Using this schema:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified" attributeFormDefault="unqualified">
	<xs:element name="root">
		<xs:annotation>
			<xs:documentation>Comment describing your root element</xs:documentation>
		</xs:annotation>
		<xs:complexType>
			<xs:sequence>
				<xs:element name="someElement" type="IdentityType" maxOccurs="unbounded"/>
			</xs:sequence>
		</xs:complexType>
	</xs:element>
	<xs:complexType name="IdentityType">
		<xs:sequence>
			<xs:element name="someOtherElement" type="xs:string"/>
		</xs:sequence>
		<xs:attribute name="id" type="xs:ID" use="required"/>
	</xs:complexType>
</xs:schema>


And this XML file:

<?xml version="1.0" encoding="UTF-8"?>
<root>
	<someElement id="id1">
		<someOtherElement> Text 1</someOtherElement>
	</someElement>
	<someElement id="id2">
		<someOtherElement> Text 2</someOtherElement>
	</someElement>
	<someElement id="id3">
		<someOtherElement> Text 3</someOtherElement>
	</someElement>
	<someElement id="id4">
		<someOtherElement> Text 4</someOtherElement>
	</someElement>
	<someElement id="id5">
		<someOtherElement> Text 5</someOtherElement>
	</someElement>
</root>

I get null on getElementById. This class demonstrates the problem:
public class TestXercesId {
	private DocumentBuilder builder = null;
	
	public static void main(String[] args) {
		URL schema = TestXercesId.class.getResource("/test-xerces.xsd");
		TestXercesId test = new TestXercesId(schema);
		InputStream xml = test.getClass().getResourceAsStream("/test-xerces.xml");
		Document doc = test.parse(xml);
		Element id3 = doc.getElementById("id3");
		System.out.println("id3: " + id3);
	}
	
	private TestXercesId(URL schemaURL) {
		DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
		factory.setAttribute(
				"http://apache.org/xml/features/validation/dynamic",
				Boolean.TRUE);
		factory.setAttribute(
				"http://apache.org/xml/features/validation/schema",
				Boolean.TRUE);
		factory.setAttribute(
				"http://apache.org/xml/features/validation/schema-full-checking",
				Boolean.TRUE);
		factory.setAttribute(
				"http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",
				schemaURL.toExternalForm());
		try {
			builder = factory.newDocumentBuilder();
		} catch (ParserConfigurationException e) {
			throw new RuntimeException(e);
		}
	}

	private Document parse(InputStream xmlDocument) {
		try {
			return builder.parse(xmlDocument);
		} catch (Exception e) {
			throw new RuntimeException(e);
		} 
	}
}
