Well the test is 'current practice' ... as far as I can tell URN
is still being defined. Does any UA support METHODS or TITLE?
METHODS I'm lukewarm about, but I would have thought TITLE had far too
much potential to get rid of.
Like LINK, I guess, it's only now becoming apparent what you can do
with it. I'd like to see browsers recognise
<link href="..." rel="sibling" title="Minority report">
or
<a href="..." rel="toc" title="Inhaltsverzeichnis">...</a>
In the first case, the button or whatever could be dynamically labeled
with the TITLE; in the seocnd, it could be a flash which lights up as
the pointer passes over the highlight.
