usage of block-progression-dimension.minimum

Hi all,

I'm trying to create a block that has a minimum heigt of 37mm by using
'block-progression-dimension.minimum' attribute in this way :


<fo:root xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:oecd="
http://oecd.metastore.ingenta.com/ns/" xmlns:cover="
http://www.oecd.org/ilibrary/cover" xmlns:functx="http://www.functx.com"
xmlns:svg="http://www.w3.org/2000/svg"
   xmlns:fo="http://www.w3.org/1999/XSL/Format">
   <fo:layout-master-set>
      <fo:simple-page-master master-name="simple" page-height="297mm"
page-width="210mm" margin-bottom="0mm" margin-left="0mm" margin-right="0mm"
margin-top="0mm">
         <fo:region-body/>
      </fo:simple-page-master>
   </fo:layout-master-set>
   <fo:page-sequence master-reference="simple">
      <fo:flow flow-name="xsl-region-body">
[...]
<fo:block-container position="absolute" top="245mm" left="80mm"
width="115mm" border="0.75pt solid black"
block-progression-dimension.minimum="37mm">
    <fo:block margin="3mm" font-family="Arial" font-size="11pt"
line-height="15pt" linefeed-treatment="preserve"
white-space-collapse="false">United Nations Industrial Development
Organization<fo:inline font-style="italic">, et al.</fo:inline> (2009),
“Employment and Social Protection”, <fo:inline font-style="italic">OECD

external-destination="http://dx.doi.org/10.1787/journal_dev-v9-art1-en"
text-decoration="underline" color="#507AAA">
http://dx.doi.org/10.1787/journal_dev-v9-art1-en</fo:basic-link>
    </fo:block>
</fo:block-container>
[...]
     </fo:flow>
   </fo:page-sequence>
</fo:root>

but it does not work, when the content is not long enough the dimension of
the block is less than 37 mm.

Thank you for helping
Best regards
