Description:
------------
---
From manual page: http://www.php.net/class.soapheader
---
The SoapClient::SoapHeader() doesn't work as it declares in php.net document.

Test script:
---------------
$wsdl = 'http://demo-hotelws.touricoholidays.com/HotelFlow.svc?wsdl';
$client = new SoapClient($wsdl, array('trace' => true));

$var = array(
		'LoginName' => 'xxxx',
		'Password'  => 'yyyy',
		);
$ns = 'http://schemas.tourico.com/webservices/authentication';
$soapheadervar = new SoapVar($var, SOAP_ENC_OBJECT, null, null, null);
$soapheader = new SoapHeader($ns, 'AuthenticationHeader', $soapheadervar);

$client->__setSoapHeaders($soapheader);
$body = array(...);
$response = $client->SomeFunction($body);
echo "Request:\n".$client->__getLastRequest()."\n";
echo "Response:","\n",$client->__getLastResponse(),"\n";

Expected result:
----------------
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://tourico.com/webservices/hotelv3">
  <SOAP-ENV:Header>
    <m:AuthenticationHeader xmlns:m='http://schemas.tourico.com/webservices/authentication'>
      <m:LoginName>xxxx</m:LoginName>
      <m:Password>yyyy</m:Password>
    </m:AuthenticationHeader>
  </SOAP-ENV:Header>
  <SOAP-ENV:Body>
    ........
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Actual result:
--------------
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://tourico.com/webservices/hotelv3" xmlns:ns2="http://schemas.tourico.com/webservices/authentication">
