Good, Good.

Yes, DOM currently is language agnostic, however the optional
className parameters aren't compatible with languages which can't do
that.  So as defined now getElementsByClassName would not manage to do

However there's a good argument for making an ECMAScript specific DOM,
as it would be more natural for the majority of ECMAScript programmers
who use it, but that would mean redefining most of the HTML DOM into
something neat in ES eyes.
