hi,

you don't need any extension, just use the right way :
when one need an xml-structured variable, just put it as a child of the 
root element of your stylesheet, and refers to it by using document('')
the sole constraint is to define a namespace for all your structured 
constants :

<xsl:stylesheet xmlns:const="*** My datas ***"
     xmlns:xsl="...as usual">

<const:fonts>
   <font>
       <fontcolour>Red</fontcolour>
       <bgcolour>Blue</bgcolour>
   </font>
   <font>
       <fontcolour>Black</fontcolour>
       <bgcolour>White</bgcolour>
   </font>
</const:fonts>

<xsl:template ...>
<xsl:variable name="fontNumber">
   <xsl:choose>
     <xsl:when test="SOME TEST">1</xsl:when>
     <xsl:otherwise>2</xsl:otherwise>
   </xsl:choose>
</xsl:variable>
<xsl:variable name="font" 
select="document('')/*/const:fonts/font[number($fontNumber)]">
<td bgcolor="{$font/bgcolour}">
   <font color="{$font/fontcolour}">
     TEXT
   </font>
</td>
</xsl:template>

</xsl:stylesheet>
