Docs are truth in the way that if you don't follow them and have trouble Oracle says you are wrong in the way you did it, correct that according to the docs.
And I agree bugs in docs are legion.

That's what I wanted to mean.

| FWIW, IMNSHO I don't think Oracle has appropriate quality control.
| The QC of the docs has improved noticeably over time, but it _is_ a
| tough, perhaps intractable, problem keeping them totally correct.
| Now, in your first response you said the procedure is not public.
| Yet, anyone can look at the script that creates it. What does not
| public mean?

I never lock the door of my garden, this does not mean you are allowed to enter.
