[jsr-314-open] Adding an extension mechanism to the JavaScript event data payload

And as long as I'm discussing the JavaScript event data payload, one
thing that got stripped out during the specification process was the
ability to extend the payload object in a compatible way.
At least one of the proposals I made was to simply prefix any property
to the object that's implementation specific with a "x". Another way
could be defining a "extension" object that's a property of the data
object, hanging all impl specific properties off of there.
If we don't have that extension mechanism, then adding something like a
description property to that object becomes a compatability problem -
since a future version of the spec may add a description property,
breaking existing apps.
Again, I think that defining something like this could fall into an Errata.
Thoughts?
I've filed Issue 571 to track this issue.
