I'm not sure if you have in mind the semantics of a link, or the user experience of a link.

The interaction model doesn't have to be that of a link to still reflect the semantics of the referenced text. A screen reader could simply read the referenced content when the user chooses to see a description, including all the usual cues it would if reading that markup directly, but then return you to where you were in the document. I tend to think that would be a better user experience than a model where you follow a link and then navigate back.
