A class selector is a type of attribute selector; it selects an
element whose class attribute is equal to some value. For example, I'm
writing a document now that has an element with a class of "mission"
on a handful of lists.

The class attribute is an element identifier (like id). HTML 4.01
says:

You seem to think it's something else entirely; what that is I'd like
to know.
