Yes, that's the technique I have been using so far.  It seems to me
that Richard would disagree here.

Easy.  Just consider the HTML document attachted below.  RTF has
similar features, but I chose HTML, because that is more widely
known.  To see where the problem is, you need a CSS capable browser
on a GUI.

However, I don't think we need to talk about specific solutions /now/,
for this reason:

Yes, I agree.  If all this is basically a question of whether a box
model (in the display engine) is too much work and trouble, then in
fact, I suggest to delay such decisions until basic functionality is
implemented by means of space and newline characters.  Then we'll see
whether what's left is worth it.

I am thinking about an architecture (for word processing) that should
be modular enough to replace the spaces-and-newline box model with
something real without trouble.
