Governments do this all the time. THey don't just say "you need a  
wheelchair ramp", they say at what angle it can be, how wide it has to be,  
how much space you need to turn around. They say things about how many  
steps you can have between a landing, and how big the steps have to be.  
Most of the time they don't say a thing about colour, because it doesn't  
matter. But every so often there is a case where they do. There are laws  
about font sizes in documents (for example, if your conditions of use are  
displayed at less than 10 point in the state of New South Wales, they  
cannot be held to be binding on anyone supposed to read them - so all you  
folks whose sites have 9.6pt small print, take note).

In other words, most laws tend to be about outcomes for people, not about  
ticking boxes. Lawyers are experts in how to interpret things in these  
terms to suit their argument of the day. Judges are experts in  
interpreting these things to ensure that the collection of interpretations  
is consistent and sensible. Technical experts provide the information that  
can be used for this interpretation. Why would there be a different  
approach to the web?
