I did use the "5/31/05" Data Model to create the Information Model.

I thought I have captured all the elements from the DOM in the IM - 
which ones are missing?

I can see where the Distribution/messageElement relationship is 
different - i assume this is because
the Message is optional - should be "0..*" on the relationship.

Also, the only difference in the messageElement/content relationship is 
the "OR" in the DOM
and not in the IM (This is a UML issue - may have to use a dependency 
class- anyone know how to
express OR in UML?)

I don't see that as an issue at all - at the *modelling* level.

At the XML level - is the concern that the following:

<distribution>
  <targets>
   <keyword>...
  </targets>
</distribution>

Is more complex than:

<distribution>
    <keyword>...
</distribution>
