The problem is that that that doesn't support the use-case of copying
existing XML-SVG into text/html, since no such SVG uses //<![CDATA[

I see two solutions:

1. Support <![CDATA[]]> while tokenizing CDATA.
2. After having read the data from the DOM, strip a leading
'<![CDATA[' and trailing ']]>' before handing the data to the CSS/JS
engine.

Good point, that would even further reduce the risk that pages out
there would break.
