20  * Represents the sharedRelationships element within the UDDI version 2.0 schema.
21  * This class contains the following types of methods:
22  *
23  * <ul>
24  * <li>A constructor that passes the required fields.
25  * <li>A Constructor that will instantiate the object from an appropriate XML
26  * DOM element.
27  * <li>Get/set methods for each attribute that this element can contain.
28  * <li>A get/setVector method is provided for sets of attributes.
29  * <li>A SaveToXML method that serializes this class within a passed in
30  * element.
31  * </ul>
32  *
33  * Typically, this class is used to construct parameters for, or interpret
34  * responses from, methods in the UDDIProxy class.
35  *
36  * <p><b>Element description:</b>
37  * <p>This is a collection element that contains zero or more keyedReference elements.
38  * These elements form part of the RelatedBusinessInfo structure.
39  * The RelatedBusinessInfo structure is a response message to the
40  * find_relatedBusinesses inquiry message.
41  * The information in the keyedReference and businessKey elements, for a specific
42  * businessEntity (present in relatedBusinessInfo structure), represent complete
43  * relationships when they match publisher assertions made by the publisher for each
44  * businessEntity.
