Hi Jonathan

There is a method that works for XEP formatter. The trick is to set block-progression-dimension to image height. See code below

   <fo:block-container block-progression-dimension="3in">
    <!--  wrapping container with height sufficient for inserted image -->
    <fo:table width="100%" table-layout="fixed">
     <fo:table-column column-width="80%"/>
     <fo:table-column column-width="20%"/>
     <fo:table-body>
      <fo:table-row>
       <fo:table-cell border-style="solid" height="50%">
        <!-- Set height to 50% of available area  -->
        <fo:block>A</fo:block>
       </fo:table-cell>
       <fo:table-cell number-rows-spanned="2" border-style="solid">
        <fo:block>
         <fo:instream-foreign-object height="100%" baseline-shift="-10%"
          content-height="scale-to-fit" scaling="uniform" role="checked checkbox">
          <svg:svg width="1.2in" height="2.7in" viewBox="0 0 100 300">
           <svg:text font-family="Helvetica" font-size="50" text-anchor="start" x="2" y="100">SVG</svg:text>
           <svg:text font-family="Helvetica" font-size="42" text-anchor="start" x="2" y="200"
           >Image</svg:text>
          </svg:svg>
         </fo:instream-foreign-object>
        </fo:block>
       </fo:table-cell>
      </fo:table-row>

      <fo:table-row>
       <fo:table-cell border-style="solid" height="100%">
        <!-- The 50% of area is already allocated, so set height to the rest of it - 100% of available area  -->
        <fo:block>C</fo:block>
       </fo:table-cell>
      </fo:table-row>

     </fo:table-body>
    </fo:table>
   </fo:block-container>

But it fails for FOP formatter (the version I tried is 0.93). Here is a part of its log:

SEVERE: Cannot find LM to handle given FO for LengthBase.                                                      16:06

WARNING: The contents of row 1 are taller than they should be (there is a block-progression-dimension or height cons
traint on the indicated row). Due to its contents the row grows to 14400 millipoints, but the row shouldn't get any
taller than MinOptMax[min=opt=max=0] millipoints. (fo:table-row, location: 17/21)

Maybe you should ask about similar trick for FOP in fop-user@xmlgraphics.apache.org mailing list.
