The point is that in the model the only distinguishing key between the  
capabilities is the standardID, so if there are two capabilities in  
the same resource with the same standardID there is nothing to  
distinguish the two capabilities apart from the human readable  
description - this works in an interactive situation where there is a  
human to point at the capability that they want, but not if you are  
writing a non-interactive script.
