I don't understand. Why can't we use xyzparams="" if we introduce an XYZ

As we add algorithms, we would presumably add the attributes if they are 

Note that right now a browser isn't intended to just add more algorithms 
willy nilly; the list is theoretically limited to what's in the spec. If 
we were to make the list open-ended, we could just as easily allow the 
attributes to be open-ended as well.
