You might want to use nested grammars for avoding conflicts.  For example:

start = foo
foo =
  grammar {
    start = foo
    foo = element foo { empty }
  }

In this schema, we have two definitions of "foo".  But the first  and 
the second belong to different grammars and thus they do not conflict.

Cheers,

Makoto
