+ * <p>

+ *
+ * <h2>Usage Example 1</h2>
+ * <p>
+ * Say: http://localhost/hello?wsdl has reference to
+ * <p>
+ *   &lt;xsd:import namespace="urn:test:types" schemaLocation="http://localhost/hello?xsd=1"/>
+ *
+ * <p>
+ * Using this class, it is possible to write A.wsdl to a local filesystem with
+ * a local file schema import.
+ * <p>
+ *   &lt;xsd:import namespace="urn:test:types" schemaLocation="hello.xsd"/>
