2 * \brief 'po.xsd' is in 'purchase' namsespace. Without elementFormDefault="qualified" all local elements are in default namespace and not in
3 * target namespace.
4 *
5 * <p>elementFormDefault="qualified"</p>
6 * <ul>
7 * <li>Without this in 'po.xsd', a local element declaration (such as that for shipTo, billTo, items) refers to an element in no namespace,
8 * rather than an element in the target namespace</li>
9 * </ul>
10 * <h3>Test1</h3>
11 * <ul>
12 * <li>po.xml specifies every element in 'http://www.freemindcafe.com/purchase' namespace and hence validation fails.</li>
13 * </ul>
14 * <h3>Test1</h3>
15 * <ul>
16 * <li>po-default.xml specifies every element in default namespace except purchaseOrder and comment (These being not the local element in po.xsd belongs
17 * to targetNamespace.) and hence the test passes.<li>
