The following seems to do what you want, note there is no explicit 
recursion, or parameters involved, applying-templates just takes care of 
everything just as easily following attribute references as walking the 
trr via child relationships:


<xsl:stylesheet  version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

<xsl:key name="c" match="Category" use="@ID"/>
<xsl:variable name="c" select="document('Categories.xml')"/>
<xsl:template match="Entry">
<xsl:text>&#10;</xsl:text>
<xsl:value-of select="Date"/>
<xsl:apply-templates select="key('c',CategoryID,$c)"/>
<xsl:text>;</xsl:text>
<xsl:value-of select="Recipient"/>
<xsl:text>;</xsl:text>
<xsl:value-of select="Value"/>
</xsl:template>

<xsl:template match="Category">
 <xsl:apply-templates select="key('c',@ParentID,$c)"/>
 <xsl:text>;</xsl:text>
 <xsl:value-of select="en"/>
</xsl:template>

</xsl:stylesheet>
