Rik is correct: listing items at-risk is done before entering CR, and
is often done when the LC review period indicates that a particular
feature is poorly understood, non-interoperably implemented by two or
more implementors who don't want to change, has unforseen and poorly
documented interactions with other features, and so on.

So it is commonly done between exiting LC and entering CR.

Dirk is correct that a complete and detailed list of changes is
required. Generally, the disposition of comments document will explain
the rationale for the change.

As Cameron mentioned after the call, there needs to be a complete
disposition of comments for all comments received since LC was
published (this includes threads that started before LC and are still
being discussed.

In the case where changes/feature requests were requested but denied
(or moved to a next version) there also needs to be a mail from the
editors asking for confirmation that no change/deferred is okay (and
preferably, confirmation back from the commentor).

If no change was requested and none made then its enough to just
record the comments and note that no change resulted.

Tests are not required before entering CR (but are encouraged). Having
an idea of what tests are needed, a test plan etc and a rough estimate
of how long this might take, is information that must be in the
transition request for CR.

That sounds good

Given one of the last call comment from tav, the disposition of
comments could usefully add that information (everything you can do in
SVG1 you can do with this, right?)

OK so now I am confused again; the test plan includes tests in SVG and
HTML, but compositing for SVG and HTML is deferred to level 2?
