Description:
------------
I tried to use php-soap extention with a wsdl 2.0 format file and I discovered that the parser only understand old wsdl 1.1 format.

The 1.1 format documentation is there :
http://www.w3.org/TR/wsdl

A wsdl 1.1 example :
http://devzone.zend.com/node/view/id/689#Heading7

The 2.0 format june 2007 w3c recommandation is there :
http://www.w3.org/TR/wsdl20/

A wsdl 2.0 example :
http://en.wikipedia.org/wiki/Web_Services_Description_Language#Example_WSDL_file

Reproduce code:
---------------
<?php
$client = new SoapClient(
    '/path/wsdl/example.wsdl'
);

Actual result:
--------------
PHP Fatal error:  SOAP-ERROR: Parsing WSDL: Couldn't find <definitions> in '/path/wsdl/example.wsdl' in /path/client.php on line 4
PHP Stack trace:
PHP   1. {main}() /path/client.php:0
