   Andrew Tanenbaum's Computer Networks book (with the Orange cover, second
   edition (?)) contains about 10 pages of overview of ASN.1.  In there he
   mentions that an addendum to the original ISO 8824 draft includes explicit
   support for bounded array declarations.  I'm curious whether anyone knows where
   to find additional information about this addition to the ASN.1 spec?

If you order IS 8824 from ISO or your favorite standars outlet (ANSI,
perhaps), Addendum 1 will be included.  I'm quite sure that they are
fully willing to sell you only the addendum.  It's usually referred to
as ISO 8824A1.  The addendum also adds support for macroes and other
nice stuff that it became pretty obvious was needed when the standard
was applied outside of ISO.  CCITT X.208 contains these by default.
This makes cross-reference between the two "technically aligned"
standards somewhat difficult, but it works.

I would suggest ordering the CCITT version rather than the ISO version
with addendum.  It's in the X.200 fascicle of the Blue Book.  ANSI
also sells these, I know.

The ISO texts (IS 8824/5 + addenda) cost four times more than the
CCITT texts, and the CCITT come in a nice blue soft cover, with the
entire X.200 series recommendations, as well.  You may want to save
some money, this way.
