Boris, Yes, absolutely you have found a hole in the combination of CSS spec plus SVG spec. Various W3C committees (CSS, SVG, CDF) have discussed this issue extensively in coordination with each other during the past several months. I know there are detailed proposed wording changes within the various committees, but right at this moment I am not sure I remember all of the details about which language is going into which spec and when the new language will make it into public specs. Maybe others will provide details. One aspect that I remember is there is an ultimate fallback in case CSS does not specify an absolute length value and SVG either specifies or defaults to 100%. In this case, as I remember the ultimate default is 300px width by 150px height, which I believe is consistent with existing Mozilla implementation. (But you would know this better than me.)
