I think that everything can be solved with this advice: ignore 12.4 
entirely, and just look at the last example in 12.1.2.  I'll add some 
text to 12.4 about simple markup substitution.

(I can't remember exactly what it was you wanted to do, but I had the 
impression that it was simple and was most easily created like the 
example in 12.1.2)

Yes.  Err... actually, I'm not sure.  This is why you should keep emails 
on the mailist.
