interpreting success criterion 1.3.1

hi everyone, 

 

I am interested in the group's thoughts regarding interpreting success
criterion 1.3.1.

 

In my sphere of operation, this success criterion is typically satisfied by
using UL, TH, and H-1-6. 

 

That is, the success criterion is interpreted proscriptively as a
requirement to use selected elements of structural mark-up, but only for a
very limited set of relationships and/or  structures.

 

Does anyone know of a taxonomy of 'relationships'? Or is the definition of
relationships as 'meaningful associations between pieces of content'
open-ended?

 

Cheers, 

Adam
