but with a CSS binding, you should not expect the 2nd to work, since you 
can't work out the cascade until it's in the document, I agree with pure 
name binding in sXBL it's a different issue.

Equally, I can't think of any scenario without custom methods where it 
matters (therefore there's no need to decide this for sXBL, and we can wait 
to decide on this behaviour until a complete XBL specification.)

Do you have an actual use case why - I'm struggling to really see it, and 
can think of many situations where having the bind events before it's in the 
document are problematical (anything that relies on sizes etc. from the 
document.  You'd certainly get considerable complications, and start having 
to track mutation events as the element was inserted into the document.  I 
think it would be much easier to say that the binding happened on insertion.

Cheers,

Jim.
