Maybe as a starting point, but it looks incomplete compared to what one would expect that tools need.
E.g. the grammar generated for the Eclipse PHP Plug-in
is at least with an order of magnitude finer (but the grammar files were not published :( ).
The grammar available for JavaCC is also pretty simple.

I see. It looks rather new :).
