In code like: <fo:table-cell border-top-color="black" border-top-width="0.5pt" border-bottom- color="black" border-bottom-width="0.5pt" border-left-color="black" border- left-width="0.5pt" border-right-color="black" border-right-width="0.5pt"> .... There is not border rendered for the table cell using .20.4.
You forgot to specify border style, which is "none" by default and what effectively means just no border, as in this case border-width value is forsed to be 0. See http://www.w3.org/TR/xsl/slice7.html#border-top-style.
