-- 5.4.1.2:  "relative units are computed to absolute values", at the 
Computed Value stage
-- 5.4.1:  "converted to an absolute value if necessary", at the Used Value 
stage

Having checked CSS2,
-- the first convert-to-absolute (5.4.1.2) refers to things like % to NVDC.
-- the second convert-to-absolute (5.4.1) refers, for example, to things 
that are defined as a percent of the actual display box to be used.

There isn't any contradiction.  But it's confusing (and that's the way it's 
written in CSS2).
