[whatwg] False orthogonal nature :read-only and :disabled in WF2

[Rikkert Koppes]

Either I am rather confused or there are some misunderstandings still. 
Some observations:

(1) If :read-write does not apply to disabled controls, :read-only does 
(since it applies to all other html elements - meaning they are mutually 
exclusive). Hence :disabled implies :read-only (not vice versa for the 
record) and hence :disabled and :read-only are not orthogonal.

The spec now says :read-write does not apply to input elements that do 
NOT have the readonly attribute specified AND that are NOT disabled, or 
in other words (by mutual exclusivity), :read-only applies to input 
elements that have the readonly attribute specified OR are disabled.
