What about my suggestion at the WWW/TEI meeting to have 4-6 different
kinds of emphasis.  For instance <em1>,<em2>... or <em a>, <em b>....
The different kinds wouldn't neccessarily be any kind of precedence
order but would simply specify DIFFERENT kinds of emphasis for each
of the tags.  That way you could specify different words to be
emphasised and be sure that each emphasis style will be unique.

The problem is that there is only a limited number of ways to
show emphasis, especially on non graphical terminals, so if you
define 20+ kinds of logical emphasis they all get mapped to a
smaller set of physical styles.  In many cases you could specify
two different logical emphasis and they will get rendered
EXACTLY the same.  As a document writer it would be nice to be
able to know that text marked with different emphasis tags
will indeed be shown in a different styles.  Specifying a 
smaller set of somewhat logical emphasis tags that will have
unique physical renderings will solve this problem.
