Re: XBL 2.0 implementation made available for major browsers

Laurent et al,

I thank you very much for the feedback provided and the attention payed.

Yes, as many of you guessed, the shadow content (the one coming from XBL template) of course doesn't become anonymous while is inserted into the hosting language DOM. Yes, this IS a problem, since the specification clearly says on where it should go (anonymous content is of course one of the key features of the language). However when used carefully even that "ugly" trick can be worth of the other benefits. (There is many use cases that do not even require templating, right?)

I thought you got it, if not, see the goals of the implementation:
- draw attention to XBL 2.0, the only "extension point" for DHTML today
- let folk experiment with the technology, many people still do not get the sense of technology

And yet, do not forget we all leave in a real world, world of coming out IE8 locked on DOM-0 etc.

This is a great work, congratulation !

However, your implementation of XBL2 is not full : nodes added from an 
XBL are not anonymous, and this is a big issue. Because many DOM 
properties and methods don't return expected results. For example 
mynode.firstChild should not return a node added by XBL.

But unfortunately, I think you couldn't fix this issue, unless browser 
provide API to create anonymous nodes... (In Gecko, there is a such API, 
but it's an internal API).
