Check my last response to this, but there's a very good use for ID to a
style sheet that will apply to only one particular object (per document).
For instance, news sites. They have Headlines on their news stories. If you
want all Headlines to look similar, you use a linked style sheet that
defines Headlines. That doesn't mean that there's multiple headlines on a
page though.

While they could just as easily define one particular instance with a class,
sometimes it's just cleared to have one particular ID.

I might be mistaken and the CSS docs specifically say that IDs should be
used if there's going to be multiple ones, but I would imagine they
recommend you to use classes if you're going to have similar elements on a
single document.
