Both XEP and FOP draw the red rectangle.
With XEP its left and top edges are placed on the left and top edges of the
paper sheet (page viewport area), while with FOP they are placed on the
left and top edges of the page reference area (ie the page minus the page
margins).
I think the result produced by FOP is correct with respect to the XSL-FO
Recommandation, but I am not sure, and I would be pleased if somebody could
give his opinion.
Yes, FOP is right, XEP used to interpret absolute as fixed. It will be compliant
with the next feature release (coming soon).
