Kenneth: given that "initial-scale" refer to what you call "CALCULATED  
initial-scale" because of this part from 6.1:

"Computed values refer to the computed values from the property  
definitions. Other values refer to the values resolved/constrained to at  
that point in the procedure. The values are initially resolved to their  
computed values."

Am I right to assume that I can keep the wording, but swap 11 and 12?
