I don't know that anyone has set out to check all the definitions.
Like you, people have been reporting problems to the DSSSList as they
find them.

The documentation project is not that systematic, you would not be
reinventing the wheel, and anything you could contribute would be more
than welcome.

People have contributed to the DSSSL Documentation Project at various
times (see the contributors page) but there isn't really a "they"
beavering away on the Documentation Project right now.  If you, or
anyone else, have something that you would like to contribute or would
like to contribute but don't know what you can work on, feel free to
contact me.  I would dearly like more people to contribute to the
Documentation Project.
