That is interesting. Authoring and Delivery ratings?
I can see how a plugin might rate itself but how does the content 
declare how complex it is? For instance X3D has statements to tell 
level of capability required but the player doesn't know this until it 
loads the file and looks at some properties. Likewise the plugin can 
report its capabilities but you must ask some specific questions when 
it is already running. If the plugin fails or declines then it is 
probably late for the <object> fallback so recovery may get 
complicated. Actually the data in the content file are "Profile" that 
tells the basic level of features ranging from Interchange to Full, 
and "Component", like H-Anim, that brings in other structure and 
capabilities. But the plugin cannot report until it is running and the 
file info is not visible to the player until the file is loading.

Thanks and Best Regards,
