Hi Roy,

Welcome to the DOM community. These days we mostly hang out in
https://github.com/whatwg/dom and https://wiki.whatwg.org/wiki/IRC.

It's unfortunately not very clear, but you want to study
https://dom.spec.whatwg.org/ instead.

It's not a correct name, but since it was only ever used by
attributes, changing the type of the things it holds is actually
possible. Having said that, we might have to change Attr objects back
to being Attr node objects. It's a little up in the air.

You're correct that it's a little weird, but unfortunately we cannot
right all wrongs, just a handful.
