AFAIK, you can't create your own, true, superglobals.  Thus, there'd be no way to specify the variables_order for an userland var like $_XML (since it's not really a superglobal)

Yeah, but even an auto_included file is much later than when the real superglobals get created.  To emulate user defined superglobals at runtime, I've done the nasty:

$_SERVER['XML'] = array('new','york','php');

function foo() {
   echo implode('-',$_SERVER['XML']);    new-york-php
}


Which keeps an array named XML out of the global namespace; otherwise, $GLOBALS is probably best.
