I've been reading the new draft standard of XHTML 2.0, and in the midst of wading through obscure tags that I was shocked to realize have been part of HTML for a decade without ever being used but are still there, was reminded of a couple things we could do:
Interlanguage links should produce <link> tags to go in the <head> section, such as: <link title="This article in Swahili" rel="alternate" lang="sw" href="http://sw.wikipedia.org/..." />
And also: <link title="Printable version" rel="alternate" media="print" href="http://....?printable=yes" />
and perhaps: <link title="Wikipedia copyright" rel="copyright" href="http://www.wikipedia.org/wiki/Wikipedia:Copyrights" />
Will it have any practical results? I dunno. But it sounds exciting and standards-compliant!
