Yuck! Change! Bad! July 8th
from Safari fame is trying to defend some of the extensions the Safari/WebCore team made to the HTML standard. Those changes (which they even submitted to the Working Group) were deemed necessary to support the classy styles and animation in Dashboard, a new desktop accessory collection to make its first appearance in Mac OS X 10.4 “Tiger” (which they already got a lot of beating for for different reasons).
Dave’s post is definitely a worthwhile read, especially since he’s talking about the alternatives they had to extending the HTML standard and the reasons those had been dropped for.
