Description:
------------
When making a connection to a Soap Web Service (WSDL-mode), in which the WSDL is using two .XSD schema imports, both with different namespaces, the PHP soapClient doesn't add the second namespace into the Soap Request, specifically it does not add them to the <SoapEnvelope> section of that request.

Pulling up the same endpoint in SoapUI it works properly, but PHP receives an error as it's missing the additional namespaces.


SoapUI generates this:

<soapenv:Envelope 
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:epis="http://www.testsite.com/testService" 
xmlns:com="http://www.testsite.com/common/dto/common">

Where PHP generates this:

<SOAP-ENV:Envelope 
  xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:ns1="http://www.testsite.com/testService"


As you see the above PHP generated header leaves out the second namespace entirely.


Expected result:
----------------
PHP's request should contain both namespaces based off of the WSDL as below within the SoapEnvelope:

<SOAP-ENV:Envelope 
  xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:ns1="http://www.testsite.com/testService"
  xmlns:ns2="http://www.testsite.com/common/dto/common">
