Because IE 6.x will behave like IE 5.5 if it is in quirks mode, any hack used to account for the differences in behaviour between IE 6 in standards mode and Win IE 5.x will not work as planned. Be sure that your HTML document will be interpretted in standards mode in IE 6 if you are going to use this hack (or others like the High Pass Filter, Simplified Box Model, or Inline High Pass Filter).
Putting whitespace in the comment will have the same effect.
This hack is used in some of the Alternate Box Model Hacks.
