says:
# All a elements that have an href attribute, all area elements
# that have an href attribute, and all link elements that have an
# href attribute, must match one of :link and :visited.
A number of user agents have recently implemented changes to
handling of :link and :visited that can't be described strictly in
terms of an element matching a selector. These are described in
more detail in http://dbaron.org/mozilla/visited-privacy .
css3-selectors has an exception that allows this:
# UAs may therefore treat all links as unvisited links, or
# implement other measures to preserve the user's privacy while
# rendering visited and unvisited links differently.

HTML5 should have a similar exception that allows user agents to be
more flexible than requiring that all of the elements listed match
exactly one of :link and :visited.
