Using substring call with for-each/apply templates

I have the following code in my xslt;

<td>
        <xsl:for-each select="RFQLastDate">
                <xsl:apply-templates/>
        </xsl:for-each>
</td>

I would like to apply the substring function to take the first 11
characters of the contents of "RFQLastDate".   How do I proceed?
