But seriously. As a user and an implementor, despite the fact that I
have not only read the spec several times, I actually *wrote those
words*, I think it's absolutely clear that the semantics implied by
naming the attribute 'select' are so overwhelming that if we don't
intend them, we must rename this attribute.

Though I'd prefer to simply remove it.

Do we have a use case that actually justifies this complexity?
