Re: REL and REV attributes (Was: More comments on HTML 3.0)

Regarding a "backup" tag/entity, this is solvable by the browsers with
information you can make available today. Here's an example file:

<HEAD> ...
<LINK REL="Precedes" HREF="next.html">
<LINK REV="Precedes" HREF="prev.html">
<LINK REL="Subdocument" HREF="top.html">
.... </HEAD>
<BODY> ...
<A HREF="top.html">Table of contents</a> --
<A HREF="prev.html">Previous chapter</a> --
<A HREF="next.html">Next chapter</a>
... </BODY>

Now, if the browsers sees a match between an anchor and a link with
the relationship REV="Precedes" or REL="Subdocument", it can do its
history manipulation trick. Assuming the user has checked that option,
of course :-)

The framework for this has been available since the first HTML
specification, I think. <LINK> is probably the most ignored tag by
browsers in all of HTML. Something like Ian Graham's document control
button bar would be a great help. Make sure Author is on the list.
<LINK REV="made" HREF="mailto:..."> is one of the most frequently
encountered <LINK> constructs, thanks to Lynx.
