/**
 * @file woden_types_element.h
 * @brief Axis2 Types Element Interface
 * This interface represents the &lt;wsdl:types&gt; element. 
 * It supports parsing, creating and manipulating a &lt;types&gt; element.
 * <p>
 * The data types used in WSDL elements are typically defined within a 
 * &lt;types&gt; element using a type system such as W3C XML Schema.
 * Schemas may be imported or inlined within &lt;types&gt;.
 * A &lt;types&gt; element may contain multiple schema import elements with
 * the same namespace attribute, so the schemaLocation attribute may be used 
 * to distinguish them.
 * Likewise, it is valid to have multiple inline schemas, so the id attribute 
 * may be used to distinguish them.
 *
