Not really.  DRY refers to content, not structure.  Unlike content,  
we should repeat structure as much as possible (for different  
content).  That's what makes it standardized and useful.

However, there is an issue with defining scope (i.e. how do we limit  
the scope of hCard photos to the hCard and not affect a surrounding  
hAudio?) that we keep running into whenever anyone suggests re-use of  
property names.  There's an effort to solve that problem started here:


But that's moving slowly precisely because we keep avoiding the  
problem instead of addressing it.  But it's a solvable problem.   
Parsers can figure out the difference between hCard photos and hAudio  
photos, even though they're not doing so yet.  If it becomes a  
significant problem, it will be solved by clarifying parsing rules.   
If it doesn't become a significant problem, it's not worth worrying  
about.  Either way, it needn't influence our choice of property names.
