  <para>
   This is a low level API function that is used to make a SOAP call. Usually,
   in WSDL mode,
   you can simply call SOAP functions as <classname>SoapClient</classname> 
   methods. This method useful in non-WSDL mode when <literal>soapaction</literal> 
   is unknown, <literal>uri</literal> differs from the default or when sending
   and/or receiving SOAP Headers.
  </para>
  <para>
   On error, a call to a SOAP function can cause PHP to throw exceptions or return a
   <classname>SoapFault</classname> object if exceptions are disabled.
   To check if the function call failed to catch the SoapFault exceptions,
   check the result with <function>is_soap_fault</function>.

  &reftitle.returnvalues;
  <para>
   SOAP functions may return one, or multiple values. If only one value is returned
   by the SOAP function, the return value of <literal>__soapCall</literal> will be
   a simple value (e.g. an integer, a string, etc). If multiple values are
   returned, <literal>__soapCall</literal> will return
   an associative array of named output parameters.
