The D.R.D. is a D.T.D. *plus* additional logical properties of the D.T.D.
For instance, you may wish to say which tags are "sectional tags",
so that sectional cursor motion can be implemented in a straightforward way
or so that they can be exported in a uniform way to LaTeX.
Currently, the D.R.D. mainly manages important properties like
the arity of a tag, which children are accessible by the cursor, etc.
More things, like block/inline properties and environment variables
should be added within not too long. Documentation should also be
completed slowly but surely.

At the moment, I have no time for this. I would already be happy to
have a decent and well document interface in Scheme. I also more and
more believe that Scheme is a great scripting language for TeXmacs.

This will be under thorough discussion with Henri Lesourd as soon as
version 1.0 of the graphics mode will be ready.
