ERT Action Item: researching previous efforts for location and persistency of test results

Attached is an HTML document that discusses some ideas for locating 
accessibility errors within HTML documents. It can also be found at:
http://checker.atrc.utoronto.ca/errorid.html

In summary, I'm suggesting that we use XPointer to describe accessibility 
errors when we don't care about persistence. When we do care about 
persistence, such as recording user judgments, we use a fuzzy pointer based 
upon element and attribute values.

Everything is open to modification so please take a look and post your 
comments to the list.

Cheers,
Chris
