try something like this

Capture original and current value in a description

<update_task_event>

  <task_event>

    <event_sequence />

    <task_id>@task_id</task_id>

    <description>Reassigned from @expression[Original(person_id)] to @person_id</description>

    <event_type>REASSIGNED</event_type>

    <insert is_initialized="False" />

  </task_event>

</update_task_event>

here is another example

<update_request_event>
            <request_event>
                  <request_id>@request_id</request_id>
                  <event_type>DOWN</event_type>
                  <user_def1>@expression[Original(user_def2)]</user_def1>
                  <user_def2>@user_def2</user_def2>
                  <insert/>
            </request_event>
</update_request_event>
