I would call the methods with the appropriate parameter, as documented.

Yep thanks for your help, just needed to make the following change

    $method        = SOAP::Data->name('web:processRequest')
        ->attr({'xmlns:web' => $uri}),
;

Strictly speaking, that ain't necessary :)

#!/usr/bin/perl --

use strict;
use warnings;

use SOAP::Lite;

#~ use SOAP::Lite 0.65 +trace => 'debug';
use SOAP::Lite +trace => [ 'all', '-objects' ];

my $soap =
  SOAP::Lite->proxy( 'http://localhost/blah/DummyService', timeout => 
+1, );

my $serializer = $soap->serializer();
$serializer->register_ns( 'http://mydummy.namespace.localhost', 'mns' 
+);

my $data = [
    SOAP::Data->name('mns:test'),
    SOAP::Data->name( 'mns:description' => 'an item in my namespace', 
+)
      ->type('mns:mytype')
];

print $serializer->envelope(
    method => @{ $data }
), "\n";
    
warn "\n", '-' x 66, "\n";
my $som = eval { $soap->call( @{$data} ) };
warn "\n", '-' x 66, "\n";
