028 * Characteristics that may be associated with a {@link FeatureType}.
029 * This interface is the parent type of {@linkplain AttributeType attribute type},
030 * {@linkplain FeatureAssociationRole feature association role} and {@linkplain Operation operation},
031 * but not feature type.
032 *
033 * <p>Property types typically define the following properties:</p>
034 * <ul>
035 *   <li>A name and a human-readable description.</li>
036 *   <li>The type of values (in {@link AttributeType} and {@link FeatureAssociationRole}).</li>
037 *   <li>Number of allowable occurrences of the value (in {@link AttributeType} and {@link FeatureAssociationRole}).</li>
038 *   <li>A default value (in {@link AttributeType}).</li>
039 * </ul>
