I no longer recall exactly what the original context was, and don't
feel it's worth rummaging about on g's groups to find it.  Maybe the
root of it was that you use 'bound' (here, anyway) in a sense that I
wouldn't: that's 'referenced', which includes bound as a distinct subset. 
Have I picked up a not so common distinction somewhere along the way?
