I'm using SOAP::Lite in a client which consumes a SOAP service over which I have no control. Traditionally, I've used code like this:

  
my $response;
eval {
  $response = $soap_handle->call('MyMethod', $security_token, $datagra
+m);
}};

if ($@) {
  print "Error: SOAP call died: $@. \n";
}

When the method doesn't call for any arguments, I just pass undef in $datagram, and it worked just fine, producing XML like this:

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope blah blah blah>
  <soapenv:Header>
    <wsse:Security blah><blah>blah</blah></wsse:Security>
  </soapenv:Header>
  <soapenv:Body>
    <MyMethod xsi:nil="true" />
  </soapenv:Body>
</soapenv:Envelope>

Recently, the vendor has updated their web service, and they no longer accept the xsi:nil="true" attribute.

How can I suppress that nil attribute using SOAP::Lite, so that my tag looks more like this?

  <soapenv:Body>
    <MyMethod/>
  </soapenv:Body>
