predefined variable use

All throughout the manual predefined variables are used. The most common format (currently) is simply relying on register_globals and prepending a $ to them, such as $PHP_SELF and $DOCUMENT_ROOT. Because 4.2.0 defaults register_globals off, this will change. My question is, do we use $HTTP_SERVER_VARS or $_SERVER for these. My opinion is we use $_SERVER yet not mention it's specific to 4.1.0+ everywhere as that's a ton of little notes. Too many. But, this is still an issue, how should it be addressed? If $_SERVER simply linked to the superglobals page, that should be enough, right? Or can we easily do that, how? Or is it time to not worry about it. Regards, Philip Olson p.s. imho predefined server variables should remain registered by default in 4.2.0 and beyond. ;)
