You might have a look at a paper of mine that just appeared in the
International Conference on Compiler Construction in Sweden. It is
entitled, "Maptool -- Supporting Modular Syntax Development".
It discusses a tool that maps between concrete and abstract syntax
fragments and automatically generates a parsing grammar that will
construct the right abstract syntax tree given any input.
In addition to appearing in the proceedings of the conference (published
by Springer Verlag), the paper can be found from the following URL:
