Customise Shipment Event XSL

Hi,

I have taken DefaultShipmentEventHtml.xsl from OTM, Renamed it as ShipmentData.xsl. I want to edit the XSL and add more information available on Attribute 1 to the XSL. I have added the following the XSL.

Code Change

<tr>

<td width="170" height="25"><fontface="Verdana, Arial, Helvetica" size="2"color="000066"><xsl:value-ofselect="translator:get-notification-value('Attribute1', string($language),string($country), string($variant))"/></font></td>

<td><fontface="Verdana, Arial, Helvetica"size="2"><xsl:value-ofselect="Shipment/attribute1"/></font></td>

</tr>



Output
Ship Date :2014-08-12 09:19:03 Europe/Paris
Attribute1:

Eventhough data is present on shipment/attribute1 in the xml. This is not getting displayed in the email notificaiton.
Let me know if i missed anything.
