Currently IE does not support transparency on PNG images at a bit depth
greater than 8. There's a "filter" that can be applied that allows
transparency but only if the IE version is 5.5+. If it's less than 5.5 I
need to use an albeit poorer quality 8 bit PNG.

I'm using a conditional comment to "know" it's IE. Should I just use
another conditional comment to "know" if the version is less than 5.5,
or is there a better way?
