Description:
------------
This has been reported before #40318 and marked as bogus but it is not 
bogus - it simply fails to work as expected.
When using soap classes the generated xml header does not have the 
namespace prefix for all the tags.
When creating a soap header the soapVar is passed. The xml that is 
generated has the correct namespace prefix for the outer tag that is 
generated but the inner tags have no prefix. Bug #40318 suggests that 
the namespace cannot be guessed for the inner tags. I am suggesting that 
the namespace for the inner tags surely can be assumed from the outer 
tags namespace. The suggested workaround did not work for me. My 
workaround was to roll my own xml.

Reproduce code:
---------------
class AuthHeader {
	private $UsernameToken;
	public function __construct($username,$password) {
		$this->UsernameToken = new AuthDetails($username,$password);
	}
}
class AuthDetails {
	private $Username;
	private $Password;
	public function __construct($username,$password) {
		$this->Username = $username;
		$this->Password = $password;
	}
}
$auth = new AuthHeader('xxx','xxx');
$security_ns = 'http://namespace';
$authvalues = new SoapVar($auth, SOAP_ENC_OBJECT);
$header = new SoapHeader($security_ns, 'Security', $authvalues);


Expected result:
