This class contains functionality used by the ID class
in the version 2.3.0, 2.3.1, 2.4, and 2.5 packages
Note: The class description below has been excerpted from the Hl7 2.4 documentation. Sectional
references made below also refer to the same documentation.
The value of such a field follows the formatting rules for an ST field except
that it is drawn from a table of legal values. There shall be an HL7 table number
associated with ID data types. An example of an ID field is OBR-25-result status.
This data type should be used only for HL7 tables (see Section 2.7.6, "Table").
The reverse is not true, since in some circumstances it is more appropriate to use
the CE data type for HL7 tables.
