I am converting my XML-to-DDML converter to be an XML-to-XMLSchema
converter. So far it is pretty smooth going.

The draft is missing information (especially declarations in the appendixes)
on the following:

* ordered
* unordered
* boolean and so on

I have a suggestion for the enumerations.  It would be better to be able to
declare a bag of literals, and then assign enumeration properties to the
literals:

<bag name="days">
    <literal  enum="holiday">Sunday</literal>
    <literal  enum="working long-weekend-holiday">Monday</literal>
    <literal  enum="working">Tuesday</literal>
    <literal  enum="working">Wednesday</literal>
    <literal  enum="working">Thursday</literal>
    <literal  enum="working">Friday</literal>
    <literal  enum="us-holiday ">Saturday</literal>
    <literal  enum="tw-working">FirstSaturday</literal>
    <literal  enum="tw-holiday">SecondSaturday</literal>
</bag>
<datatype name="holiday">
    <enumeration>
        <bag name="days" />
    </enumeration>
</datatype>
<datatype name="working">
     <enumeration>
         <bag name="days" />
    <enumeration>
</datatype>
<datatype name="tw-working">
     <enumeration extends="working" >
              <bag name="days" />
    </enumeration>
</datatype>

Whether it would be better to have "extends" or elements to do set
operations on datatypeRef elements I dont know.
