My mistake.  I was looking in the Docbook 4.1 DTD when I
thought it was 4.1.2.  So the PUBLIC ID does change
with each digit, as it probably must for precision.

I don't think there is a clear solution for all situations.
There are times when you need the ID to be precise, and
there are times when you can tolerate some flexibility.
If the tools could just read your mind ...  ;^)
