My opinion is that it is better to keep this kind of information out of 
line. I sent an explanation of why to the DC-Accessibility mailing list 
yesterday, and will look for a URI or forward it here, but the basic 
idea is that there may be several people recording results and you want 
to know what the different evaluations say. (It's also cleaner).

Tools for implementing this way include Annotea 
http://www.w3.org/2001/Annotea - a protocol that has three-and-a-half 
server implementations and at least a handful of clients already.
