[fitsbits] NOST 100-2.0

[Steve Allen]

'tis probably a bit late to mention it, but I've just noticed
something in NOST 100-2.0 which leaves me wanting for a clarification.
I'm looking at the version dated March 29, 1999, which is, I believe
the most recent version.

Section 5.4.1.1 is titled "Principal".  The word is used again in the
paragraph that follows, but it is not defined anywhere that I've seen
in the document.  It is used interleaved with the term "primary", which
is defined.

Principal is also used in point 18 of Appendix E.  This usage appears
simply to be maintaining self-consistency, and adds nothing to the
comprehension.

Most confusing, however, it is used in Table F.1 in a location where
I would expect the use of the word "primary".

What is "principal" supposed to mean, and how is it different from "primary"?
