You're the expert on these issues. I'll take a stab at it and you can 
correct as necessary.

This isn't just an SVG issue. It is a generic XML issue for any language 
which might want to allow internal CSS stylesheets. For example, XHTML has 
the same issue.

The CDATA around an internal CSS stylesheet is not always necessary but is 
highly recommended. Many CSS stylesheets do not use any special XML 
characters such as ">", but because the CSS language offers the possibility 
of conflicts (such as ">"), it is highly recommended that all internal CSS 
stylesheets be embedded within a CDATA construct.

Implementations should accept internal CSS stylesheets that are either 
inside of a CDATA node or within a text node. It seems to me that all W3C 
specifications that have a <style> element (e.g., SVG and XHTML) should 
state this explicitly. I will propose that the SVG spec explicitly mention 
that internal style sheets should be processed in either of two scenarios: 
(a) when embedded within CDATA or (b) not embedded in CDATA.
