Hi Loretta, Late me take a crack at these two. RE DEFAULT The default presentation is what most users get when they go to the site for the first time with a browser that is set up in the form it comes when you install it. (e.g. no user preferences set). RE: There may be relationship that appear in the default presentation that don't have to be perceived to understand the content If they author presents the relationships to most users (even if not all need them all) then the relationships should be provided for all. They are information - therefore they should be perceivable even if view not using the expected/standard/default means for viewing. Make sense?

It isn't well defined what the default presentation is 2. There may be relationship that appear in the default presentation that don't have to be perceived to understand the content An example of the latter would be structural information in an image, where the information is communicated via alternate text.

I think it needs to be perceivable structures relationships in the content that can be perceived from the default presentation. RATIONALE What we are trying to achieve is to make sure that any relationships that are obvious from the presentation - are also obvious when looking at the markup. Yes?
