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.
