It's the only one that's ever been voiced without the extreme
prompting now generating some. The WHAT specifications (like the W3
specifications, indeed most specifications) are creating features, and
never voicing why they're necessary, the use cases are simply not made
- there probably are use cases for them, but they _must_ be voiced,
otherwise you simply cannot review them.

No such requirement exists in web-browsers today, why are you suddenly

This use case is fulfilled by the -moz-binding and similar proposals,
it does this more successfully (as it does not lead to the
inconsistent UI problem) I don't see the point in having both
className selectors and -moz-binding XBL approaches, but thanks for

I don't agree that it's necessary to do this, one of the historic
problems of the DOM in the ECMAScript context (and others) is that
individual language strenghts are not gained. There is nothing
obviously wrong with having language specific API's.

Do some binding languages not require the type of the parameter to be
specified as either an array or a string?
I do not personally see the use case for a class specific operator,
either a CSS Selector method, that selects on any CSS selector, or
nothing seems appropriate.
