Documentation problem with page.tpl.php

I feel that the documentation is a bit confusing for us non-php types. When I look up documentation for variables I like to copy/paste them into the my code. Unfortunately I miss understood the change that was made from D6 to D7. I think it would be helpful if the documentation explained that the new print regions variables need to be placed inside a render(); to work properly.

I suggest changing "Regions:" to "Regions ( to be place inside render(); ):".

If someone has better wording feel free to suggest it.
