Work on ACID4 has started

“Acid4 will be primarily a visual test, not especially scripted. Focus will probably be on SVG, CSS, and mixing namespaces, probably with the main document being an XML file with an SVG root element. Work on Acid4 will begin when three of the four top rendering engines have builds that pass the test, and will be finished and announced after four of the top four rendering engines have announced that they have fixed all the bugs found by Acid3” (src) Be sure to read the list “LESSONS FROM ACID3”. Lolz!
