Re: SVG 1.1 and CSS3 Units and Values


this old CSS draft still has some funny proposals
in it, not useful for SVG and not useful for
CSS-animation and -transforms as well.

For example for the angle type is noted:
"Angle values should be normalized to the range 0-360deg by the user agent. 
For example, -10deg and 350deg are equivalent."

If authors want to have an animation with more than one turn or
in a defined direction from a negative to a positive angle or vice versa
this results in nonsense.

Open question: What happens for an animation from 0 to 360deg?

Therefore I think, this old draft is quite useful for a CSS world without
animation, but not for CSS with animation or for SVG. It needs a
careful update.

Other problems may occur with numbers in scientific notation or
the different approach for lengths and units for example.

Such an update of the CSS draft would be a good chance to
adjust it to the SVG recommendations ...
