W.r.t. validity map, then unlike what I say there, non-empty @alt in 
combination with role=presentation should IMO be valid. This would be 
in line with thoughts I have heard from you that ARIA is for making 
content accessible and authors should not be prevented from making 
content accessible with ARIA.

However, as sole content inside a link, it should probably be invalid 
to use role=presentation.
