/**
 * Represents the find_relatedBusinesses element within the UDDI version 2.0 schema.
 * This class contains the following types of methods:
 * 
 * <ul>
 *   <li>A constructor that passes the required fields.
 *   <li>A Constructor that will instantiate the object from an appropriate XML
 *       DOM element.
 *   <li>Get/set methods for each attribute that this element can contain.
 *   <li>A get/setVector method is provided for sets of attributes.
 *   <li>A SaveToXML method that serializes this class within a passed in
 *       element.
 * </ul>
 * 
 * Typically, this class is used to construct parameters for, or interpret
 * responses from, methods in the UDDIProxy class.
 *
 * <p><b>Element description:</b>
 * 
 * <p>This message returns zero or more relatedBusinessInfo structures. For the
 * businessEntity specified in the find_relatedBusinesses class, the response
 * reports that business relationships with other businessEntity registrations
 * are complete. Business relationships are complete between two businessEntity
 * registrations when the publishers controlling each of the businessEntity
 * structures involved in the relationship set assertions affirming that
 * relationship.
