The title also has a specific machine readable use for the link element.

"The title <http://www.w3.org/TR/html4/struct/global.html#adef-title>attribute
has an additional role when used with the
LINK <http://www.w3.org/TR/html4/struct/links.html#edef-LINK> element to
designate an external style
sheet.<http://www.w3.org/TR/html4/present/styles.html#style-external>Please
consult the section on links
and style sheets
<http://www.w3.org/TR/html4/struct/links.html#linksandss>for details."
