It was pointed out to me during an FXTF telecon that the CSS2.1 spec conflicts with SVG in section "6.4.4 Precedence of non-CSS presentational hints", specifically this section: # For other languages, all document language-based styling should # be handled in the user agent style sheet. -- http://www.w3.org/TR/CSS21/cascade.html#preshint Wrt cascading, the SVG spec says the following: # For user agents that support CSS, the presentation attributes must # be translated to corresponding CSS style rules according to rules # described in Precedence of non-CSS presentational hints ([CSS2], # section 6.4.4), with the additional clarification that the # presentation attributes are conceptually inserted into a new author # style sheet which is the first in the author style sheet collection. # The presentation attributes thus will participate in the CSS2 # cascade as if they were replaced by corresponding CSS style rules # placed at the start of the author style sheet with a specificity # of zero. In general, this means that the presentation attributes # have lower priority than other CSS style rules specified in author # style sheets or ‘style’ attributes. -- http://dev.w3.org/SVG/profiles/1.1F2/publish/styling.html#UsingPresentationAttributes To make this section of CSS2.1 more SVG-friendly, I suggest rewriting 6.4.4 as follows: | For other languages, all document language-based styling must | be translated to the corresponding CSS and either enter the cascade | at the user agent level or, as with HTML presentational hints, | be treated as author level rules with a specificity of zero | placed at the start of the author style sheet. Then SVG or other specs can simply write something like | ... presentational attributes are treated as author-level rules | according to the rules described in Precedence of non-CSS | presentational hints [CSS21:6.4.4] ~fantasai
