I agree. I also think a mechanism like this will first be useful for
automatically generated trees of information, like those made by
LaTeX2HTML.
I thought this resource was well known, but it sounds like it isn't:
[http://www.w3.org/hypertext/WWW/MarkUp/Relationships.html]
|   Link Relationship values
|   
|   Status: This list is not part of the standard. It is intended to
|   illustrate the use of link relationships and to provide a
|   framework for further development.
This specifies "Made" for author, "Precedes" for next _and_ previous
and a number of others. Shouldn't we take notice to that second
paragraph?
