was: End-of-lifing dead documents in /TR/ [marking drafts]

Hi all,
can we also look at marking drafts and other docs not in /TR/ clearly as
OUTDATED USE LATEST XXX as these hang around and turn up in search results
example:

http://www.w3.org/WAI/WCAG20/quickref/20070517/

perhaps a wiki page could be set up to list outdated docs for triage?

actualy found this doc which has a clear visual indication:

http://www.w3.org/WAI/GL/WCAG20/tests/
