Description:
------------
When receiving a SOAP request, SoapServer does not properly validate if it matches the given WSDL. 

Invalid elements are simply surpressed and not passed through to the called function.

I would expect the SoapServer->handler() to raise an Exception so that the program can decide if it terminates or go ahead with all parameters it can get.

bye,

Reproduce code:
---------------
<?php
ini_set("soap.wsdl_cache_enabled", "0");

class DummyClass {
    public function __call($name, $arguments) {
        fprintf(STDERR, "Method $name was called with ".var_export($arguments, 1)."\n");
    }
}

$HTTP_RAW_POST_DATA = <<<EOF
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope 
    xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
    xmlns:ns1="http://www.foo.de/services/exampleService">
<SOAP-ENV:Body>
    <ns1:exampleRequest>
        <aaaa>1000</aaaa>
        <bbb>815</bbb>
    </ns1:exampleRequest>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>


EOF;

$server = new SoapServer("chammers.wsdl");
$server->setClass('DummyClass');
$server->handle($HTTP_RAW_POST_DATA);

Expected result:
----------------
As the request parameter "aaa" has a typo and is actually written as "aaaa" I would expect an Exception or at least some kind of warning.



Actual result:
--------------
... but the handler class just gets the "bbb" parameter:


$ php chammers.php 
Method example was called with array (
  0 => 
  stdClass::__set_state(array(
     'bbb' => 815,
  )),
)
