[ic] Stopping the IC parser early - break(), exit() or document.done()?

[Dan B]

I'd like to discover an IC tag that stops it from continuing to parse (it 
just packs up the HTML and ships it off).  Kind of like break(), exit() or 
document.done() in other languages.

[include templates/regions/checkout_bottom]

Is there something like that already?  Or is it bad design?  (I should be 
using [if]'s that cover the entire document).

Thanks,
