      This is the default type for all of the DC elements. It defines a 
      complexType SimpleLiteral which permits mixed content but disallows 
      child elements by use of minOcccurs/maxOccurs. However, this complexType 
      does permit the derivation of other types which would permit child 
      elements. The scheme attribute may be used as a qualifier to reference 
      an encoding scheme that describes the value domain for a given property.
