I'd like to hear what people think about the following:
1. Including whitelists of elements and attributes for SVG and MathML in
htmlscrubber. See my current [htmlscrubber.pm][] and the [diff][]
from the current trunk.
2. Creating a whitelist of safe SVG (and maybe even HTML) style
attributes such as `fill`, `stroke-width`, etc.
This is how the [sanitizer][] in html5lib works. It shouldn't be too
hard to translate the relevant parts to Perl.

Another problem is that [HTML::Scrubber][] converts all tags to lowercase.
Some SVG elements, such as viewBox, are mixed case. It seems that
properly handling SVG might require moving to a different sanitizer.
It seems that [HTML::Sanitizer][] has functions for sanitizing XHTML.
Any thoughts? --[[JasonBlevins]], March 21, 2008 13:54 EDT
