RE: xsl:variable with hex color values

Another solution to add to the list you've been given: In XSLT 2.0 you can
do

<td bgcolor="{if (position() mod 2) then 'black' else 'white'}">
  ...
</td>

If you want to be terse and don't mind being obscure, you can write things
in XSLT 1.0 like

<td bgcolor="#{substring('FFFFFF000000', (position() mod 2 * 6) + 1, 6)}">
  ...
</td>
