/**
 * Information about the individual and / or organization of the party.
 * The following property is conditional (i.e. mandatory under some circumstances)
 * in a well-formed metadata according ISO 19115:
 *
 * <div class="preformat">{@code CI_Party}
 * {@code   └─name……} Name of the party.</div>
 *
 * <div class="warning"><b>Note on International Standard versions</b><br>
 * This class is derived from a new type defined in the ISO 19115 international standard published in 2014,
 * while GeoAPI 3.0 is based on the version published in 2003. Consequently this implementation class does
 * not yet implement a GeoAPI interface, but is expected to do so after the next GeoAPI releases.
 * When the interface will become available, all references to this implementation class in Apache SIS will
 * be replaced be references to the {@code Party} interface.
 * </div>
 *
 * <h2>Limitations</h2>
 * <ul>
 *   <li>Instances of this class are not synchronized for multi-threading.
 *       Synchronization, if needed, is caller's responsibility.</li>
 *   <li>Serialized objects of this class are not guaranteed to be compatible with future Apache SIS releases.
 *       Serialization support is appropriate for short term storage or RMI between applications running the
 *       same version of Apache SIS. For long term storage, use {@link org.apache.sis.xml.XML} instead.</li>
