Hmmm... Microsoft-ism. [http://tinyurl.com/2x2t6]

What is firing with this event? From reading up at the above URL, it sounds
like it might be fairly benign: what happens when you disable JavaScript? If
the call has anything to do that is "mission critical" you might have a
problem; as well, since it is non-standard it may not perform as expected in
alternative user-agents, so I would be cautious of the client side
scripting... (Not saying it *is* a problem, only that it *may* be a problem)

The only other thing is that if you are MANDATED to hit Priority 2 you
can't/won't, as P2:3.2 states "Create documents that validate to published
formal grammars" (unless of course you are also using a custom DTD that
includes this non-standard scripting event)

FWIW
