I have a system in which I have a main template, that template is the core of the page. Later in that same template I include another template.

Kind of like this...
<html>
<head>
<title>Site Title</title>
</head>
<body>
Some Content Goes Here
{include file=$page}
</body>
</html>

The $page variable is populated outside of Smarty.

What I want to do is this...

MAIN TEMPLATE FILE
<html>
<head>
<title>Site Title -- {$pageTitle}</title>
</head>
<body>
Some Content Goes Here
{include file=$page}
</body>
</html>

SUB-TEMPLATE FILE
{assign var=pageTitle value="Page #2 Title" scope="global"}
Some More Content

Is it even possible to declare a variable in a sub-template to be used in the main template before the sub-template is included? Or am I going to be forced to register an output filter?

No it's not possible to use a variable before it's declared.

Perhaps you should have a closer look into template inheritance

Thanks! I did just that and it works wonderfully. I didn't even know that this was possible.

Template code and its subtemplates are rendered in the order they appear.

If you assign a varibale with root scope in a subtemplate it can be seen by all subtemplate rendered afterwards but ofcause not by templates rendered before.

You can't assign variables from a subtemplate to a subtemplate which is already rendered. That's impossible.
