// class DtObjectType:
//
// Instances of DtObjectType are an extended form of DtEntityType objects.
// They extend the DIS/RPR entity type by having an additional enumerated
// field.  The new field represents a super-set of object types, e.g.
// individual, pseudo-aggregate, true-aggregate.  The remaining fields
// (kind, domain, country, category, subcateogy, specific, and extra) are
// unchanged.  In terms of comparisons and sorting, the most significant field
// is the the new field (super type).  The order of significance (in
// descreasing order) is as follows:
//
// <super type, kind, domain, country, category, subcategory, specific, extra>
//
// The standard wildcard value (-1, indicating a match of any) applies to the
// new field in the same way as for the fields in a standard entity type.
// Enumerations for the super type are found in objTypeEnums.h.
