                implementation as the third parameter of the constructor or using the <code>setComplexTypeStrategy($strategy)</code>
                function of Zend_Soap_Wsdl. The following detection strategies currently exist:

                <listitem>
                    <para>Class <classname>Zend_Soap_Wsdl_Strategy_DefaultComplexType</classname>: Enabled by default (when no
                    third constructor parameter is set). Iterates over the public attributes of a class type and
                    registers them as subtypes of the complex object type.</para>

                <listitem>
                    <para>Class <classname>Zend_Soap_Wsdl_Strategy_AnyType</classname>: Casts all complex types into the
                    simple XSD type xsd:anyType. Be careful this shortcut for complex type detection can probably only
                    be handled successfully by weakly typed languages such as PHP.
                    </para>

                <listitem>
                    <para>Class <classname>Zend_Soap_Wsdl_Strategy_ArrayOfTypeSequence</classname>: This strategy allows
                    to specify return parameters of the type: <code>int[]</code> or <code>string[]</code>. It can only
                    handle simple PHP types such as int, string, boolean, float and so on, but allows to specify
                    nested arrays of arrays of type.</para>

                <listitem>
                    <para>Class <classname>Zend_Soap_Wsdl_Strategy_ArrayOfTypeComplex</classname>: This strategy allows
                    to detect very complex arrays of objects. Objects types are detected based on the
                    <classname>Zend_Soap_Wsdl_Strategy_DefaultComplexType</classname> and an array is wrapped
                    around that definition.</para>

                <listitem>
                    <para>Class <classname>Zend_Soap_Wsdl_Strategy_Composite</classname>: This strategy can
                    combine all strategies by connecting PHP Complex types (Classnames) to the desired strategy
                    via the <code>connectTypeToStrategy($type, $strategy)</code> method. A complete typemap can be
                    given to the constructor as an array with <code>$type</code> -> <code>$strategy</code> pairs.
                    The second parameter specifies the default strategy that will be used if an unknown type is
                    requested for adding. This parameter defaults to the <classname>Zend_Soap_Wsdl_Strategy_DefaultComplexType</classname>
                    strategy.</para>

            Zend_Soap_Wsdl also contains a parser for WSDL documents that has its main application in unit-testing and code-generation
            for SOAP Webservices (Client and Server). The following example will show how the Parser can be used:
