[xsl] format-number in Saxon 8.5

[Manfred Staudinger <manfred.staudinger@xxxxxxxxx>]

Hi list,
the stylesheet below works fine with Saxon6,
00001
00022
00333
04444
55555
but not with Saxon8
001
0022
0333
04444
55555
Any idea what's wrong with it?

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="2.0"
             xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:variable name="LF" select="'&#xA;'" />
<xsl:template match="/">
       <xsl:value-of select="$LF" />
       <xsl:value-of select="format-number(1,'00000')" />
       <xsl:value-of select="$LF" />
       <xsl:value-of select="format-number(22,'00000')" />
       <xsl:value-of select="$LF" />
       <xsl:value-of select="format-number(333,'00000')" />
       <xsl:value-of select="$LF" />
       <xsl:value-of select="format-number(4444,'00000')" />
       <xsl:value-of select="$LF" />
       <xsl:value-of select="format-number(55555,'00000')" />
</xsl:template>
</xsl:stylesheet>
