There's 3 ways.

1) Make the subbox part of the templates redirect:

[subbox.xwt]

<redirect target="x" />
<template>
    <box id="x">
        <box id="subbox_wanted" />
    </box>
</template>

Now you can access $subbox_wanted in top.xwt using $subbox[0].

2) Pass a reference:

[subbox.xwt]

<template>
    wanted_proxy = $subbox_wanted;
    <box>
       <box id="subbox_wanted" />
    </box>
</template>

Now, from top.xwt, $subbox.wanted_proxy can be used to manipulate the
$subbox_wanted box.

3) A combination of the above:

Use a reference to a parent box and have the $subbox_wanted as a child
of the parent - $subbox.wanted_proxy[0]; - which can be useful if you
have lots of internal subboxen that you want to access but don't wish it
to be your redirect target.
