Appointment Fetch With PHP

I'm suffering from brain-pain in building a fetch specification to the
appointment.fetch call in PHP.  Has anyone done this?  (I'm probably
missing something dumb).

I'm doing the following (one of my permutations):

$spec=new xmlrpcval(array(
           "qualifier" => new xmlrpcval(array(
              "startDate" => new xmlrpcval(
                 iso8601_encode(mktime(0, 0, 0, 12, 31, 2001)), 'string'
                ),
           "endDate" => new xmlrpcval(
                iso8601_encode(mktime(0, 0, 0, 12, 31, 2001)), 'string'
               ),
        ), 'struct'),
       ), 'struct');

The spec ends up looking like -
xmlrpcval Object
(
    [me] => Array
        (
            [struct] => Array
                (
                    [qualifier] => xmlrpcval Object
                        (
                            [me] => Array
                                (
                                    [array] => Array
                                        (

I notice that the third level ("[struct]") is an "Array" and not an
"xmlrpcval Object".
