Firefox and most other browsers properly enforce the case sensitivity
requirements of HTML id references. Internet Explorer does not. If you
use the common technique of clicking on form labels to see if the
properly associated form element receives focus, be sure to do this
test in something other than IE to ensure true accessibility in other
browsers.

identify this as an issue...

This is something we've already identified to be flagged in the next
version of WAVE.
