For instance the CSS parser in WebKit can easily be modified to support the SVG parsing rules on transform lists for CSS Transforms [1] on SVG presentation attributes. This includes whitespaces between function names and the first opening brace, comma or whitspace separation of arguments or functions and so on. I wouldn't be happy to write the parser for transform functions twice. (Nearly) all browsers engines support scientific notations for numbers on SVG presentation attributes and like I wrote before: I bet no one implemented the CSS parser a second time just for SVG presentation attributes! The last part is the quirks mode. I am sure that no one wants to maintain a second parser for quirks mode. Even if just some properties differ. Therefore css3-syntax should be aware of all this.

Where are rules like the "whitespace is allowed between function name
and parenthesis" written?  I can't find any detailed syntax
descriptions in the SVG spec.
