Yeah. Sorry I responded at the wrong place.

If we can have a solution where authors get to use stroke-width="4"  
in XML content and are required to use "{stroke-width: 4px}" in  
stylesheets, then I'm happy. I would be happier if CSS hadn't  
required units on <length>s, but I have a sneaking suspicion that  
that won't change.

[of course I mean requiring units in CSS stylesheets, not that all  
objects must be stroked with four pixels :]

BTW - I'm not speaking for the SVG WG here.
