FO border-end-width conditionality discard

I need help with border-end-width conditionality.  I think this is
what I need.  The below table-row is the last in a set of table-rows.
The table will repeat many times on the page.  So, this last table-row
block border needs to be discarded when it appears last on each page.
Am I doing this right?  Must not be, it isn't working for me.


                    <table-row>
                        <table-cell number-columns-spanned="5">
                            <block
border-end-width.conditionality="discard" border="solid 1px #000">
                                <leader />
                            </block>
                        </table-cell>
                    </table-row>


Thanks,
Karl..
