I believe you'd need to do something like this unless you plan on
post-processing the document:
-----------------------
<html>
<head>
[% head_items = {} %]
[% temp_holding = INCLUDE foo # this will create keys/values in head_items %]
[% ### look at head items hash and display the items you need ### %]
[% INCLUDE header_stuff %]
</head>
<body>
...
[% temp_holding %]
...
</body>
</html>
-----------------------
The head_items hash is needed to get around the cloning done in INCLUDE.
(Cloning is done at the top level only, so references aren't affected.) If you
are ok with "foo"'s variables being imported into the current template, you can
simply use PROCESS and not have to worry about head_items.
