/**
 * Represents the tModelInstanceDetails element within the UDDI version 2.0 schema.
 * This class contains the following types of methods:
 * 
 * <ul>
 *   <li>Constructor passing required fields.
 *   <li>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>SaveToXML method. 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>Support element used as a container for tModel references within a
