Yet getElementById is defined as [2]:
<blockquote>
Returns the Element that has an ID attribute with the given value. If
no such element exists, this returns null.
If more than one element has an ID attribute with that value, what is
returned is undefined.
</blockquote>
Therefore... the appropriate behaviour for
getElementById("duplicate-ID") is to return null.

Mistake reported by Jim Ley on IRC:
What getElementById('duplicate-ID') returns is undefined according to the
DOM3Core recommandation. This is an error affecting the entire reply.
Apologies.
IMHO, DOM 2 Core has a better wording in regards to this: "behavior is not
defined if more than one element has this ID". It's much clearer.
