/**
 * ADT_A20 - Bed Status Update (Event A20).
 * This event is use for Certain nursing/census applications need to be able to update
 * the Patient Administration system's bed status.
 * <p>Represents a ADT_A20 message structure (see chapter 3.2.20). This structure contains the 
 * following elements: </p>
 * 0: MSH (Message Header Segment) <b>SINGLE_COMPULSARY</b><br>
 * 1: SFT (Software Segment) <b>MULTIPLE_OPTIONAL</b><br>
 * 2: UAC (User Authentication Credential) <b>SINGLE OPTIONAL</b><br/>
 * 3: EVN (Event Type Segment) <b>SINGLE_COMPULSARY</b><br>
 * 4: NPU (Bed Status Update Segment) <b>SINGLE_COMPULSARY</b><br>
 * This class provides mechanism to validate message against HL7 v 2.8.2 standard.
 * The class provides accessors & mutators for the elements mentioned above.
 * These elements can be easily populated & populated values can be easily retrieved.
 * The class has validate method which validates Message against HL7 v 2.8.2 standard.
 *
 * <p>Following is the step to create message<br>
 * Before that, respective Message Source and Message Recipient to be set on Message Factory.</p>
 * <p>ADT_A20 objA20 = (ADT_A20)MessageFactory.createInstance().createSendSupportedMessage("ADT", "A20");</p>
