Code Changes (CC) in ISO 15924

This may be a worst case scenario, which can be easily clarified, but as
it stands, there seems to be some anomalies on the ISO 14924 page on the
Unicode site, analogous to the "CS = Serbia and Montenegro" code change
debacle relating to ISO 3166.

The situation seems to be as follows:

1. ISO 15924:2004 - Information and documentation -- Codes for the
representation of names of scripts, was published on 2004-02-04.

2. According to the relevant page on the Unicode site, i.e.
http://www.unicode.org/iso15924/codechanges.html
there seem to have been some actual code changes _since_then_(marked as CC
in the final column)

3. Is this correct?

4. Were any _4-letter_ codes changed after publication?

5. Why were code changes (as opposed to clarifications) made after
publication?

6. Are there therefore deprecated 4-letter codes? (and deprecated 3-digit
codes?) None are listed in the table, though if a Code Change was made, it
implies that there was a previous code.

7. What will be done about deprecated codes when they happen, and metadata
which uses deprecated codes?

8. Can we avoid getting into the crass situation that the ISO 3166/MA got
into with the CS Code Change in ISO 3166? (I hope that the answer is Yes!)

The table is shown as text below, so that date comparisons can be made,
and some elucidation given in relation to points 1 and 2 above.
