Not really. Sadly IE6's comment parsing is _really_ strange.

Nah, pretty much every UA has slightly different comment parsing, and many 
of them suffer from the security problem I mentioned earlier today (the 
one with the comment containing hostile script being exposed through a DOS 
attack).

The comment parsing currently described in the HTML5 spec is quite simple 
and easy to implement, thankfully.
