Re: ISSUE-123: Should DOM Level 3 Events support namespaced events?

A short input from implementors.

In the Backbase Framework we do have implementation of the namespaced events (since we entirely implement DOM-Events Level 3 specification), however, to my knowledge, this featured subset is neither used by us nor by developers who use our framework.

If you decide to drop the namespaced events, please adjust the CustomEvent interface and add a "initCustomEvent" method to it, since the interface is often used and having initCustomEventNS removed would make it useless.

ISSUE-123: Should DOM Level 3 Events support namespaced events?

Raised by: Anne van Kesteren
On product: DOM 3 Events

There are several reasons for dropping namespaced events as we discussed during 
today's telcon:

* Browser vendors have not implemented them
* There has been very little to no demand from Web developers for these 
features.
* Implementing this feature increases QA cost
* Implementing this feature increases the complexity of the Web platform

The main argument in favor seems to be libraries being able to distinguish 
event types from each other. Given that they currently use a simple string for 
this purpose (dojo.xxx, etc.) and that seems to work fine having namespaces 
does not seem necessary here. There's also not infinite libraries and you won't 
use infinite libraries on a Web page so the advantage seems really slim.
