What software needs to make this distinction? A browser will display 
data if it can. A link checker will validate a link whether the

This suggests to me that distinctions based on "expected processing" are 
not very useful or helpful and arguably go against the XML philosophy 
that the data receiver decides what to do with the data, not the data
