Intrested buddies can implement plain C functions to consume what the grammer is producing. this way the rtf-grammer-tree can be converted to what is needed: GNUstep attributed strings, tex files, ...

Be aware that some functions are called at specific times when some information may or may not be available. The first argument of all functions is a context, which is asked to be maintained by the consumer at whichever purpose seems appropriate.
