---+++ Open issues identified by editors/authors
   * Should VO-DMLs *Model* extend *Package*?<br />Omar notes that this, together with XML schema usage of &lt;sequence&gt;, complicates hand-writing of models.<br />ALso, it gives Model a vodml-id element, which can cause problems with the interpretation of that concept and its uniqueness requirements in a model. [Omar: It's more like the other way around. Needing vodml-id for Model is the issue. Also, the fact that the xmls now have imports as their latest element is an annoying consequence, and not only for those "hand-writing" models. I made a couple of suggestions on how to fix this, but I believe that in the end the best approach is to go back to the previous state]
