The first time round. Once you establish the framework for a class of
documents, the payback comes from the repeatability.

I'm glad you mentioned typography, because it's a canon of markup design
that you don't provide for presentation in the document, because that
goes in the stylesheet. Until you write a book on typography or a manual
for a typographic system. Then you may need to mark something as being
in italics precisely *because* it is meant to illustrate italics. Whence
the shim I did for DocBook (which I have failed to rewrite in RNG and
distribute as promised, because I was busy with something else...Real
Soon Now... :-)
