say without fear of contradiction that the FO subgroup understands the
requirement but that we deemed it outside the scope of 1.1.
Vertical justification of this sort (aligning content on two facing
pages) is a difficult thing to implement and, as far as I know, no
existing FO implementation provides it. As our list of 1.1 features
tracks existing implementations almost exclusively, that pretty much
ensured it would be pushed off.
It would certainly be possible for FO implementators to add extensions
to do this, and once they did it would be much more likely that we would
add it to the list of features in a future version of FO. I know, for
example, that Arbortext's 3B2 composition engine does vertical
justification but doesn't have a support FO binding. But as Arbortext is
both heavily involved in the XSL-FO standard and has deep undestanding
of composition they are certainly well positioned to provide a robust FO
binding to the 3B2 engine [which would be pretty cool, in my opinion, as
3B2 is a very fast and powerful composition engine].
