You can link to an id, using a client-side specialiser:

http://site/foo/bar.html#baz

links to the element with ID=baz. You can't do that with class because
(until XLink and XPointer are more widely deployed) you can't have
multi-head and multi-tail links.

Class and id are not the same, although clearly there are similarities.
