Description:
------------
When creating a SoapServer in WSDL-Mode the server fails to import the SOAP-1.2 compliant WSDL with a error message stating that the SOAP 1.2 HTTP transport binding is not supported.
However this transport binding is necessary for clients in other languages (i.e. axis2/java) to handle the messages correctly.
Currently, the SoapServer only handles SOAP 1.1 compliant bindings correctly (using:
schema: http://schemas.xmlsoap.org/wsdl/soap/ 
transport: http://schemas.xmlsoap.org/soap/http
).
SOAP 1.2 compliant bindings require both of the following schemas to be present:
schema: http://schemas.xmlsoap.org/wsdl/soap12/
transport: http://www.w3.org/2003/05/soap/bindings/HTTP/

Reproduce code:
---------------
Set up a WSDL file with the following entries:

<wsdl:definitions 
...
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap12/"
...>  
<!-- snip : types, messages and porttype -->
<wsdl:binding name="test" type="tns:test>
 <soap:binding style="rpc" transport="http://www.w3.org/2003/05/soap/bindings/HTTP/" />
<!-- snip: binding operations and  the service element-->

Setup a SoapServer using:

<?php
  $SoapServer	=  new SoapServer( 'test.wsdl',
    array(
      'soap_version'=>	SOAP_1_2,
      'uri'	    =>	'http://example.org/test/',
      'encoding'    =>	'UTF-8',
    ));
	
  $SoapServer->setClass('test');
  $SoapServer->handle();
?>

and a testclass that handles the requests.

Expected result:
----------------
the Service should be callable

Actual result:
--------------
