I read the chapter in the manual about D.R.D.s and I am looking forward to
"a more complete formal description of D.R.D.s". 

In the light of the literate programming discussion: Is it possible to
define a D.R.D. that says "the contents of this tag are supposed to be
serialized verbatim when using the literate serialization mechanism"?

I can live with Scheme. I was just asking out of interest.

More important than a different language would be a more complete
documentation of the TeXmacs API, but I can understand that this is
a lot of work.

Good. I will join the discussion then.


Thanks again,
