Now the whole xsl doesn't work..
I replaced this:
<br />
<td><xsl:for-each select=" bioghist/bioghist/chronlist/chronitem/date" /></td>
with the code below..
<td><br />
<xsl:for-each select=" bioghist/bioghist/chronlist/chronitem/date" /><br />
<xsl:value-of select="ms:format-date(., 'dd/MM/yyyy')"/><br />
</td>
