it would be helpful to be able to use EL in the <description> tag of the (human) task node.
This will allow to create dynamical task descriptions based on the process variables.

Example:
<task name="review_task">
<description>Review order nr.#

from customer #

</description>
</task>

The main purpose is to make human task descriptions in the task list more readable and user-friendly.
Because if you have 20 task instances of the same task and they are all called "Review order from customer" it is really hard to see at a first glance which task is related to which customer.
