[jsr-314-open] AJAX library in JSF 2.0

I agree with just about everything Werner says, I'd just like to expand 
on one comment:

In the case of the client side event system - I'd originally proposed a 
system that was, to put it kindly, heavyweight.  It was unanimously 
voted down by the Ajax subcommittee (and when I say unanimous, I include 
myself in there).   I'd also proposed using the OpenAjax hub, just like 
the RichFaces guys are proposing - but that, too, was voted down, this 
time with my more reluctant consent - but with the understanding that 
bridging the two systems would be trivial - and indeed it is - I just 
posted a blog describing how to do so, and it was almost embarrassingly 
short.

So if there's something they'd like to do with client events that they 
can't currently do, I'd like to hear it.  Alexander?

As far as I'm aware, the only significant gap is that you can't cancel a 
listener in the API once it's registered - an omission that I've already 
filed a spec enhancement request for - though again, it'd be quite easy 
for a library to implement this themselves if they can't live without 
it.  But I fully anticipate that being in the 2.1 spec - adding it is as 
simple as adding a token return code to addOnEvent, and a corresponding 
cancel function.
