I fully appreciate the requirement for change bars and redlining
set forth by T Bruce, and I agree that this is certainly needed
and imporant.  But I must respectfully disagree with his specific
proposal for how to meet this need.  He suggested adding a new form
of emphasis <em strikeout>.  

In my opinion, the example Bruce provides is as good an example of
the value of semantic tagging as one could hope for.  With a semantic
tag, one document could contain both the old and the new versions
of edited passages (or you could have tagged links to the old, whatever).
From this one source, your rendered could generate either:
  1) a listing of just what's currently true
  2) a comparative listing showing just what's changed
  3) a listing of the changes, in context.

Procedural markup like <em strikeout> would not allow this.  Semantic
markup will.  I regret that I don't have a specific proposal of my own
as to how to do this markup.

best wishes
