I think CSS Rules are  implemented already for some time (David Faure did 
this, IIRC), and you have access to CSS rules via DOM methods.

Anyway, CSS model is rather "transparent" (it's not  completly broken HTML4 
model).
So, even building CSS renderer for *valid CSS/XML* is not extremly difficult 
task.  Note that you want to use CSS 2.1 specs (which fix a lot of issues in 
CSS 1.0 and 2.0)

I am not sure,though, which version of CSS is used in SVG.

me too :-)

yes, I am aware that KOffice changes to zip.
And now all my KWord files almost doubled in size :-)
// but they are still ok, comparing to MS Word .doc files
