Hi Barry,
The overflow warning comes from the region-before, whose content is
higher than the extent. You can get rid of the warning by setting the
extent to 1.37in (or making the content smaller).
If I understood your need correctly, you can achieve what you want by
making use of an elastic space, that must be as big as possible but is
allowed to be reduced down to zero.
In your example below, replace the block-container that has span="all"
and a red border and plenty of fo:block children with the following:
<fo:block-container span="all" background-color="white">
<fo:block space-before.minimum="0"
space-before.optimum="{height of the region-body}"
space-before.conditionality="retain"/>
</fo:block-container>
The block-container is to prevent the space from creating a mess with
the preceding content (a so-called fence in the Recommendation); the
conditionality must be set to retain so that the space, which starts
a reference area, isn’t discarded.
HTH,
Vincent
