How do you set the default namespace? I am using a doc/literal WSDL.

$client = new soapclient('http://localhost/wsdl/RAS.wsdl', true);

$request['RASRequest']['AuthDetail'] = array()
// code to set other elements
$response = $client->call('myoperationname', $request, 'http://www.namespaceiwant.com);

The namespace "'http://www.namespaceiwant.com" is being created and is prefixed in the SOAP-ENV but the contents of the body are not using it. How do you force it become default namespace/or be used?

Here is how the request looks (see that SOAP-Body contents have no namespace definition) -

<?xml version="1.0" encoding="ISO-8859-1"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns="'http://www.namespaceiwant.com">
<SOAP-ENV:Body><RASRequest><AuthDetail>....</AuthDetail></RASRequest></SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Here is what I would like -

<?xml version="1.0" encoding="ISO-8859-1"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns="'http://www.namespaceiwant.com">
<SOAP-ENV:Body><ns:RASRequest><ns:AuthDetail>....</ns:AuthDetail></ns:RASRequest></SOAP-ENV:Body>
</SOAP-ENV:Envelope>

OR atleast be able to add xmlns="'http://www.namespaceiwant.com" to SOAP-ENV, SOAP-Body or the first element under the Body.
