So someone wasted their time writing this patch, 'cos the facility wasn't
documented properly ?????

The terminology isn't exactly clear :-)

I hope this gets documented properly and comprehensibly!!!! I can't same
I'm any wiser from reading that as to what one needs to do (though I guess
I might be if I read it in conjunction with the hba instructions).

<RANT ON>
Might I ask again that people send patches in for the documentation WHENEVER
they add a new feature!

There is no point in adding new and wonderful things if users don't know
they exist!!!!! When someone ends up duplicating functionality 'cos they
don't know that a feature exists, that's even worse........
