Why do you say that the line-height trait should be the same for all
areas? In the line-height case the specified value (1.2) is inherited
not the computed value. Therefore I was assuming that on the areas
generated from fo elements with font-size="10pt" the line-height trait
would be 12000.

OK, happy to proceed on that basis. For what its worth I did a quick
test against xep and it seems to behave as you suggested Finn.

BTW, thanks for your patience in this exchange Finn. Certainly clarified
things for me.
