In what sense?

This should work to set the fill and stroke colors; the stroke-width 
will be a parse error.  (The example in SVG 1.1 section 7.10 using the 
"style" attribute has a similar problem).

I believe that section 6.3 the second bullet point of SVG 1.1 is 
intended to be a normative requirement that SVG properties be assignable 
via CSS stylesheets.  I agree that clarifying this may be good if it's 
not clear.

In what sense?  There's no such thing, really, past being a production 
that matches the core CSS grammar.

I believe the normative requirement is that a UA that implements SVG 
_and_ CSS must support these property names in its CSS implementation.
