Validating MenuMachine javascript menus with W3C

I love MenuMachine…love it.  I can do things with it that make me look [to my clients, anyway] like a web design guru.  For those of you not aware, Menu Machine is a GoLive extension which allows you to build javascript based menus in a WYSIWYG way.  But one thing has always nagged at the back of my mind…all the custom code that MenuMachine 2.x [MM2] writes into the page couldn’t possibly pass W3C validation.  Finally I decided to dig around at Big Bang Extensions to see if there was an easy answer to this question, and lo and behold, there is: GoLive can strip the custom code from web pages ON THE FLY as it uploads them to a server!
