This class contains functionality used by the IS 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 a ST field except that it is drawn from a site-defined (or user-defined) table of legal values. There shall be an HL7 table number associated with IS data types. An example of an IS field is the Event reason code defined in Section 3.3.1.4, "Event reason code." This data type should be used only for user-defined 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 user-defined tables.
