Re: Can we place time stamp information inside an XKMS response

Hello,

Well, you can use the MessageExtension provided for Tommy Lindberg in 
his reply,
and change the dateTime type of the new element for a base64 type:

  <complexType name="TimestampType">
    <complexContent>
      <extension base="xkms:MessageExtensionAbstractType">
        <sequence>
          <element name="DateAndTime" type="base64"/>
        </sequence>
      </extension>
    </complexContent>
  </complexType>

What do you think Tommy?

Regards,
Vicente
