RE: [Mason] Reordering output

[Jonathan S. <sw...@po...>]

There is a todo item for this feature (called "placeholders"):

   http://www.masonhq.com/docs/todo/view.html?id=120

but it probably won't happen anytime soon, so for now, I recommend using a
filter and/or a global hash to record the element values.

We do this for page titles on masonhq.com. Every page has to output,
somewhere,

   <mhq:title>My Title</mhq:title>

In the final part of the autohandler we look for this tag, grab out the
title, and insert a <title> into the output.
