Subject: UniqueId in Font Dictionaries: Why?

I've been messing around with Blue Book program #16, "Making an Outline
Font".  The author goes to considerable pains to add a UniqueId entry
to the fonts created.  His/Her comments state:

  "Determine the [font's] unique ID.  If the "base" font already
   contains a unique ID, add a unique constant to it, otherwise
   pick a unique integer and leave that value on the stack."

Now, in reading these comments, I wondered how I would pick the "unique
constant".  (The author used 1 and 2 for the two fonts created.)  Anyway,
I wrote a program to list the names and UniqueId fields of all the
resident fonts.  To my surprise, *none* of the fonts on the LaserWriter
II NTX had UniqueId defined.

So this begs the question, do I really need to stuff a UniqueId into
my outline fonts?
