Some interesting reading today!
Rather than going through stuff point-by-point I'd just make one general
observation, which is: simple is good; approachable is good. Ok, that
was two general observations.
If a newbie who knows some (web) CSS can write:
way[highway=motorway] { width: 10; color: #0000FF; }
way[highway=trunk] { width: 8; color: #00FF00; }
way[highway=primary] { width: 8; color: #FF0000; }
and click "refresh", then see the map appear as they expect, then that's
great. We have a convert.
The "implement layers through eval and z-index" stuff is clever and
architecturally neat, but doesn't pass the above test. It would be kind
of like removing <p>, <ul>, <li> and everything from HTML, simply
leaving <div> and <span>. Architecturally beautiful and utterly logical
(after all, they can all be specified in CSS), but a PITA to work with.
Similarly for the colour stuff. Having multiply operations and all of
that would be great. But it shouldn't be at the cost of rejecting a
universally known, though perhaps slightly imperfect, standard.
cheers
