Please note that this allows for:
dc.title = (dc.identifier any fish)
Which to my mind is meaningless and the grammar shouldn't allow it, but to
Mike's mind is equivalent to just:
dc.identifer any fish
As per the previous time this was discussed, the only situation it's
actually useful is:
dc.title = (a or b and c)
which otherwise has to be spelt out as:
dc.title = a or dc.title = b and dc.title = c
which is still not very difficult, especially for code generated queries,
which is and will be the majority of them, I suspect.
