+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.

+I figured out a quick hack to make HTML::Scrubber case-sensitive by
+making the underlying HTML::Parser case-sensitive:
+
+    $_scrubber->{_p}->case_sensitive(1);
