Ups! que fallo, se me olvidó poner el código!
Código:
<TD valign="top" align="left" colspan="2">
<A>
<xsl:choose>
<xsl:when test="a:propstat/a:prop[attributes:ShortcutTarget != '']">
<xsl:attribute name="href">
<xsl:value-of select="dav:propstat/dav:prop/attributes:ShortcutTarget"/>
</xsl:attribute>
</xsl:when>
<xsl:otherwise>
<xsl:attribute name="href">
<xsl:value-of select="dav:propstat/dav:prop/dav:href"/>
</xsl:attribute>
</xsl:otherwise>
</xsl:choose>
<xsl:choose>
<xsl:when test="a:propstat/a:prop[office:Title != '']">
<B><xsl:value-of select="dav:propstat/dav:prop/office:Title"/></B>
</xsl:when>
<xsl:otherwise>
<B><xsl:value-of select="dav:propstat/dav:prop/dav:displayname"/></B>
</xsl:otherwise>
</xsl:choose>
</A>
</TD>
