The ISO practice is still steeped in the tradition of paper copy. They
don't want to schedule another publication run, particularly if they
have a shelf full of unsold copies from the first printing. If you have
already bought a copy of the standard, they will send you the paper
corrigendum for free and you can patch your copy however you will.
(John's suggestion matches the practice of IBM, Digital and others in
updating manuals in that time -- the manuals are presented in notebook
form, and they ship you replacement *pages*. But the ISO practice is
cheaper.) If ISO goes to a second or third print run for a standard,
they will often incorporate the Corrigenda-to-date in the later print
runs (because that is cheaper than reprinting the Corrigenda).
The interesting thing here is that we are asking for public availability
in the same time frame as the creation of the Corrigendum. Depending on
the relative speed of the different divine mills, ITTF may suggest that
we make a *corrected* version of the PDF the publicly available one.

Well, we do have the option in the "Introduction" to the Corrigendum to
summarize and perhaps provide rationale for the changes. This is
particularly useful when a conceptually simple correction causes text
changes in a dozen different places. And where the correction itself
requires clarification, a part of the correction itself can be adding a
Note to the standard.
But, just like any editing committee that resolves ballot comments, the
committee "progresses" only the changes to the specification, and files
the issue resolutions, issue by issue, in a separate report that is just
an SC32 N-numbered document. That is standard ISO practice. It
captures the rationale for whatever changes are made, and it captures
the rationale for dismissing some defect reports with no change.
