That's what <A REL="Back" ...> and/or <A REV="Next" ...> are for.
Everything mentioned in this thread can already be handled by link  
relationships.  HTML 3.0 will be much better about using them, so  
please let's not fall victim to <SPECIAL><PURPOSE><TAG><FEVER>.  In  
terms of SGML, it's better to use structured attribute values than  
tags, when the need for continuing extensibility can be anticipated.
