Answer 1

Try

<fo:block font-size="10" background-color="#000000" color="#ffffff">DEPARTURE</fo:block>

I think you'd likely also add a font-weight="bold" then. Free Advice: <fo:block font-size="6" text-align="center">$DEPARTURETIME</fo:block> looks like not-what-you-want-xslt, but probably <fo:block font-size="6" text-align="center"><xsl:value-of select="$DEPARTURETIME"></fo:block>
