 * <div class="section">Null values, nil objects and collections</div>
 * All constructors and setter methods accept {@code null} arguments.
 * A null argument value means that the metadata element can not be provided, and the reason for that is unspecified.
 * Alternatively, users can specify why a metadata element is missing by providing a value created by
 * {@link org.apache.sis.xml.NilReason#createNilObject NilReason.createNilObject(Class)}.
 *
 * <p>Unless otherwise noted in the Javadoc, all getter methods may return an empty collection,
 * an empty array or {@code null} if the type is neither a collection or an array.
 * Note that non-null values may be {@link org.apache.sis.xml.NilObject}s.</p>
 *
 * <p>Unless the metadata object has been marked as unmodifiable and unless otherwise noted in the Javadoc,
 * all collections returned by getter methods are <cite>live</cite>: adding new elements in the collection
 * modify directly the underlying metadata object.</p>
