Keep in mind that I haven't looked at the validator implementation of
this new feature. 8-}

I was tossing around the case-sensitivity issue in my head and a way to
address it. First, I thought why not just do a lc() of the
element/attribute argument  when doing the fuzzy compare? If an error has
been thrown, and you get a full match on fuzzy compare (eg: onLoad, when turned
to "onload" would get an exact match) that would trigger a stronger
assertion message than say, "crass"->"class". Since the main difference
between XHTML and HTML is going to be case-sensitivity, after errors are
thrown from the validator's strict parser they can be treated a bit more
fuzzily. I guess what I'm getting at is I think you can safely ignore case
before you get to fuzzy matching, so you can force all arguments going
in to be one way or the other.

Also, on http://search.cpan.org/dist/String-Approx/Approx.pm
it mentions:
  "You can ignore case by adding the "i" modifier."
I didn't grok the rest of what it was saying at first glance, so that may
not be appropriate...

Hope this is in some way useful or relevant.
