The differences are in the browsers' implementation of setAttribute,
For example, using setAttribute with any of the intrinsic event
handlers.

You'll have to fill me in on that, I have no idea what is in version
2.0. There is no mention of it on the Prototype.js web site (a search
on Prototype 2.0 returns no results)
Are you saying Prototype.js will go the way of jQuery and return an
object that has a reference to an element or elements as one of its
properties? That means jQuery shaddows all the DOM methods (which I
guess Prototype.js already does quite a bit of).

You said in a previous post:

So there are now 3 APIs - these two plus writeAttribute - when no API
is necessary at all. I could count the use of observe too to replace
the buggy setAttribute('onclick', fn) in IE but that's probably going
too far. :-)

The fact that it is faster is a pleasant side effect of using the most
reliable, well supported method. It is not the sole criterion.
