There are a whole host of issues that were raised.  The agreement was to 
get simple graphics first, and then work on the othe rissues.

For example, if one allows color, how does one ensure readability by 
those who are color blind.
Similarly, if one allows gray scale, how does one make sure the result 
is understandable to those who do not perceived detailed contrast 
differences as easily.

And scripting is a nightmare all its own.

Some issues are easier.  For example, external URLs simply fail the test 
for archival representation.

Yours,
Joel
