<!--This DTD contains basic generic elements and structures used in various parts of the Time Series Universal Import Export DTD.-->
<!-- ============================================================== -->
<!--REM is a convenience entity called as an attribute when the developer needs to insert comments within the data structure.-->
<!ENTITY % REM "REM CDATA #IMPLIED">
<!-- ============================================================== -->
<!--REF is a convenience entity containing the common elements used in all REF elements.-->
<!ENTITY % REF "ID | FOREIGN_ID | NAME">
<!-- %REF is an entity that contains:
		NAME contains a label together with attribute xml:lang that identifies the language of the name data.
		ID contains an ID internal to the IMP/EXP system.
		FOREIGN_ID contains an ID external to the IMP/EXP system together with a coding scheme name.
		References are used to establish relationships between elements. For instance,
		SOMEELEMENT_REF refers to SOMEELEMENT, having the same ID, FOREIGN_ID 
		or NAME. These three ways of identification are tried in this order:
			ID
			FOREIGN_ID
			NAME
		
		SOMEELEMENT matching these IDs must exist either in import XML 
		or in destination system. 
 -->

<!--OBJ_TYPE_REF refers to object type. It may be necessary to include 
OBJ_TYPE_REF if several objects of different types may have the same ID or 
FOREIGN_ID. In this situation system should match only 
objects of correct type. 
ATT_VAL is additional type of identification. If neither ID nor
