I think this j.lang does the job.
I've also added a customized version of edit.xml below to complete the example.
The main thing I'd still like to see added is support for parentheses inside
explicit definitions. Currently adding parens in the expdef context causes
problems with parsing the start/end of expdef. Any ideas?
