Very interesting question. So far as I know, we have given _no_
thought to the question of how, using ZeeRex, to represent a database
that is a virtual union of several others. Off the top of my head, I
don't think multiple ZeeRex records would be the way to go (even if
the syntax supported it, which it doesn't). The right approach is
probably to craft a single ZeeRex record, describing the union as a
whole rather than its constituents. But I am interested to hear
others' thoughts on this.
