Re:  Get value from $Variable
whenever you have an idiom of the form


I think it's worth using a key, it might be quicker but whether it is or
isn't it makes the code a whole lot easier to read.

     <xsl:for-each select="Weekdays/Day">
          <xsl:variable name="Current_Id" select="@Id"/>
          <xsl:value-of select="$Language/Weekdays/Weekday[@Wd_Id =
$Current_Id]"/><xsl:if test="following-sibling::*[1]">, </xsl:if>

could all be replaced by:

<xsl:value-of select="Weekdays/Day/key('k',@Id,$Language)" separator=", "/>

where the key is something like

<xsl:key name="k" match="Weekday" use="@Wd_Id"/>
