Hi Cherie,

Thanks for the useful text. I have checked through ATAG 2.0 and I think we always use the term in the second sense: " File description metadata"

I wonder if a definition is really necessary since the SC referred to by MS49 doesn't appear to use the term in a different or confusing way and the existence of Evaluation and Repair Language (EARL) provides a straightforward implementation technique.

B.3.1.5 Metadata Production: Authors have the option of associating accessibility checking results with the web content as metadata. (Level AA) 
Note: The metadata format that is implemented will dictate the nature of the associated results (e.g. specific check results, summary conformance claims, etc.)
