My understanding is that it is aimed at a device at least more advanced  
than DDC, but it works through taking advantage of specific device  
characteristics. So you either have to know how to identify that a device  
can do X, or you have to use something compatible with BP1 (like using an  
object element with SVG and something simpler as a fallback, or using  
scripts that are not necessary, don't blow the memory budget, etc).

BP1 allows you to extend all kinds of things if you have device knowledge.  
One of the important questions is how you get such knowledge.
