I've mentioned this on IRC but should probably mention it here so it's in the record, so to speak.  I don't see a strong use case for an onmessage attribute.  Event handler attributes are useful for quick little things, but accepting messages from other sites seems neither quick (aside from free-for-all walls I can't think of things you'd want to do that wouldn't be fairly involved) nor little (you need the origin check at a minimum, then you have to do whatever you're going to do, and it's a lot to stuff in an attribute -- and if you're just delegating to another method, why not just set the method as handler programmatically?).  I don't think having to do it via script is particularly burdensome.
