Description:
------------
i'm trying to set up a SoapServer with an dynamic WSDL file, 
but the SoapServer class only accepts a file name and not a 
xml(wsdl) string. now my workaround is a speatly php file 
thats output wsdl string but this is "very" slow.

Reproduce code:
---------------
// My Workarond:

// -generateWSDL.php:

...
print generateWSDL(...); //returns a wsdl string
...

// -SoapServer.php:

$ssSoap = new SoapServer("http://localhost/generateWSDL.php");
$ssSoap->setClass($anyClass);
$ssSoap->handle();


// better solution, but for this the SoapServer class musst accept a xml string.
$ssSoap = new SoapServer(generateWSDL(...));
$ssSoap->setClass($anyClass);
$ssSoap->handle();
