<p>Hi folks,</p>
<p>This is the simplest envelop model I could think of</p>
<p><img src="cid:part1.5223CB34.DE6D335E@gmail.com" alt=""
width="349" height="187"></p>
<p>This class will be sitting under Classes, the same way
ModelIdentification is sitting under DataTypes.</p>
<p><u>Envelope definition</u>: Content wrapper for a collection of
possibly heterogenous DDI instances</p>
<p><u>Content definition</u>: DDI instance reference</p>
<p>Thoughts?</p>
