WCF - "Incomplete" WSDL with reference to another WSDL - php

Question

I am using SoapClient to send some data from a PHP site to a .Net WCF service.
This is my (shortened for clarity) code:
$wsdl = '/var/www/libraries/MyWsdl.xml';
$myClient = new SoapClient($wsdl);
and later, the actual call:
try {
$res = $myClient->Foo($someParameter);
}
catch(SoapFault $e){
//...
}
catch(Exception $e){
//...
}
This works great when everything is online, and the error handling works if the destination server is down on the time Foo is called.
Problem is that the SoapClient constructor fails, if the destination server is down, even though i've provided it with a static XML file with the WSDL (in oppose to a URL like "http://www.destination.com/MyService?wsdl").
I believe this is happening because the WSDL contains a reference to another WSDL:
<wsdl:import namespace="http://MyCompany.Services" location="http://www.destination.com/MyService?wsdl=wsdl0"/>
This other WSDL contains the definitions of the call parameters.
So, how can I "Inline" the second "sub-WSDL" inside the original one?
Will this allow me to create a SoapClient without initiating a connection to the destination server?
This is my service definition:
[ServiceContract(Namespace = "http://MyCompany.Services")]
public interface IMyService
{
[OperationContract]
[XmlSerializerFormat(Style = OperationFormatStyle.Rpc, Use = OperationFormatUse.Literal)]
string Foo(string myParameter);
}

You can use the single WSDL-file extension from here: http://wcfextras.codeplex.com/
Note that when using .net4.5 there should be no need for it, as the default metadata endpoint now also generates single WSDL-files in addition to the linked versions.
To do that simply add "?singleWSDL” to the URI (source: http://msdn.microsoft.com/en-us/library/dd456789(v=vs.110).aspx)
