+/**
+ * There is a bug in the translator framework that causes
+ * enumerators in xml elements and enumerators in xml attributes
+ * to be treated differently.  When the enumerator is an attribute
+ * setting the model to the default causes the attribute to be removed.
+ * With an element is causes the default literal to be placed in
+ * the tag.
+ * 
+ * The problem is wrapped up in the emf unsettable attribute as well.
+ * For attributes the eIsSet method returns false for the default value
+ * For elements the eIsSet method returns true for the default value.
+ * I don't want to have to use the unsettable option in emf since that would
+ * require that I call different api.  I am not sure yet what the bug is in
+ * the translator, so I have entered one ~KFM
