The HREF is an attribute of the <A> tag. From what I've read recently,
I think there is already an URN attribute as well in HTML, so the HREF
wouldn't need to be overloaded in picking up URNs as well as URLs.
Maybe someone who was ``in'' on the development of HTML could say what
the intention with the URN attribute was; I've only ever seen it as a
place holder for future expansion when URNs finally appear (if they ever
do!).
