XML Events basically come in handy when you want a generic markup- based way to add event listeners for custom events. For instance, if XBL was implemented in WebKit, and I had my own custom magic UI control implemented with some custom XML element, I'll likely want to fire custom DOM Events, and XML Events would be a neat way for users of my widget to listen to some of these custom events without resorting to a purely script-based approach using addEventListener(). XML Events doesn't seem terribly compelling to me, because event handling about running script, so avoiding use of script to define event handlers isn't hugely compelling. And on the other hand, it's much more verbose for very simple cases than onkeypress/onclick/ etc style event listener attributes. Furthermore, the current trend among web developers is to attach all event handlers separately in script (unobstrusive JavaScript), so XML Events seems to be going in the wrong direction by putting more event listeners back in the markup. It's a lot of ifs, but if WebKit ever supports XBL and custom DOM Events, then it'd be worth re-thinking the usefulness of XML Events in WebKit. I think XBL bindings could support onwhatever style attributes if they want to make simple cases easy for their custom events.

Re: [webkit-dev] XML Events in WebKit
Guys, thanks very much for all the comments. let me be more specific about my problem. i want to add multimodal capabilities to the webkit. I want to trigger (or communicate with) an external app based on events happening in the xhtml document. Also i want to insert custom events into the XHTML context based on results from the external process. Is there any way i can do this with current version of webkit. any pointers on what needs to be done?
