This seems about as useful as a regex C compiler, that compiles

   main() { printf ("Hello world!\n"); }

and _nothing_ else.

Just because you can make an regex for _one instanace_ of a grammer
does not mean that you can (easily) use regexs to parse a generic
format.  RTF is generic - there are MANY valid ways to say similiar
things in RTF.
