Arved,

As I read the spec, the diference is that "[i]t is an error if this 
property is not an inherited property," for inherited-property-value(). 
 For from-parent(), it is the value of that property on the parent, 
regardless of inheritance.  This is consistent with the handling of 
shorthands.  Shorthands are not inherited, so they are not an issue for 
inherited-property-value().  They are, however, an issue for 
from-parent(), so special instruction are included for their handling.
