I am _very_ sceptical about the restriction to IRIs to address a
stream of CTM content and also _very_ sceptical about the restriction
to a "notation".

Just as examples what I want to do:

  %mergemap cat people.txt | awk '{ magic here}' |
  # executes this pipe under UNIX and transforms it into CTM


  %mergemap "echo '...' | mysql --batch | ... |" x my-template ($2, $1, $4)
  # executes a MySQL query and uses the my-template to generate CTM content

I do not think that preempting the syntax of %mergemap (and/or
%include) is the way to go....
