min/max values for filters

We have been looking at the filters chapter and believe that there would be a benefit for setting min/max for some of the attributes.  We are recommending these as currently, without these bounds, most browsers would likely peg the CPU so badly, it would lead it to be inoperable, or are reasonable limits a developer would want or a  user could perceive.  We'd like to see these expressed in a future version of the filters specification, but would like to see it documented.

feConvolveMatrix:  Order (Kernel Units) 
Min : (1, 1) 
Max: (10, 10) 

feConvolveMatrix, feSpecularlighting , feDiffuseLighting: Kernel Unit Length  
Min: 0.1
Max: 10

feMorphology: Radius
Max: 150

feTurblulance: numOctaves
Max: 10

Any input is appreciated.
