my $soap = SOAP::Lite
    -> ns( 'http://www.w3.org/2001/XMLSchema-instance', 'xsi' )
    -> ns( 'urn::sdp:profilemanager:requestmanager', 'a' )
    -> ns( 'urn::sdp:profilemanager:contract:110308', 'b'  )
    -> uri($uri)
    -> on_action( sub { join '.ProcessMessage', 'urn::sdp:profilemanag
+er:requestmanager:100818.ProfileScopeServiceContract', $_[1] } )
    -> proxy($url);


And here I assume I'm specifying the name of the first element with the Soap Body - Request. 

<code>
my $method = SOAP::Data->name('Request')
    ->attr({xmlns => 'urn::sdp:profilemanager:profilemanagerrequestman
+ager:100818'});
