Actually it does, since browsers aren't as strict as the standards they 
"implement". The only real reason I can think of to remove ASP tags, would 
be to unclutter php.ini. As has often been mentioned here in internals, 
there is such a thing as "too much features". Apparently that goes for 
things like OO and typehinting, and as far as I'm concerned it also goes for 
php.ini (which is also why magic_quotes are being removed altogether 
right?). If that reason (and the tinyest speed improvement in PHP when it 
searches for an open tag) is not enough reason, then I guess it's better 
kept in.
