Re: Interpretation of border and padding for blocks in XSL-FO 1.0

Antenna House and RenderX are right IMO. Apache FOP does the same. The
start-indent property (which is 0pt in this example for all three blocks)
controls "the distance from the start-edge of the content-rectangle of
the containing reference-area to the start-edge of the content-rectangle
of that block-area." Note that it's always the content rectangle that is
mentioned. Also compare that to the "Geometric Definitions" under 4.2.3.
The rest can be deducted from 5.3.2, I think. If you take the formula
for determining margin-corresponding:

margin-corresponding = start-indent - inherited_value_of(start-indent)
- padding-corresponding - border-corresponding-width

-13pt = 0pt - 0pt - 10pt - 3pt.

I'm not sure if this is the right way to explain it, but it's how I
understand it. HTH
