I've created a signature that looks like this:

signature' => array(array($xmlrpcArray, $xmlrpcInt, $xmlrpcInt,
$xmlrpcString, $xmlrpcInt, $xmlrpcInt))),

and set  $GLOBALS['xmlrpc_null_extension']=true to enable null-value
parameters.

I would like to fill only some of the parameteres. So I try to pass null
values to the method. But xml-rpc says that null can't be passed to a no-nil
parameter? What's the use for null parameteres then?

It seems that I need to make an empty signature to be able to pass variable
number of parameteres? But I would prefer a signature that validates the
input.

So in short: Is it really not legal to pass nil values to a non-nil
signature parameter?

Thanks in advance.
