+I'm allowing for inline SVG on my own installation.  I've patched my
+copy of htmlscrubber.pm to allow safe MathML and SVG elements (as
+implemented in html5lib).  <del datetime="2008-03-20T23:04-05:00">Here's a patch
+if anyone else is interested.</del>
+<ins datetime="2008-03-20T23:05-05:00">Actually, that patch wasn't quite

+
+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
