/**

 * The class for individual properties (also designed as character, type or

 * category) of observed phenomena able to be described or measured. It also

 * covers categories of informations on {@link TaxonNameBase taxon names} not

 * taken in account in {@link NomenclaturalCode nomenclature}.<BR>

 * Descriptions require features in order to be structured and disaggregated

 * in {@link DescriptionElementBase description elements}.<BR>

 * Experts do not use the word feature for the actual description

 * but only for the property itself. Therefore naming this class FeatureType

 * would have leaded to confusion.

 * <P>

 * Since features are {@link DefinedTermBase defined terms} they have a hierarchical

 * structure that allows to specify ("kind of") or generalize

 * ("generalization of") features. "Kind of" / "generalization of" relations

 * are bidirectional (a feature F1 is a "Kind of" a feature F2 if and only

 * if the feature F2 is a "generalization of" the feature F1. This hierarchical

 * structure has nothing in common with {@link FeatureTree feature trees} used for determination.

 * <P>

 * A standard set of feature instances will be automatically

 * created as the project starts. But this class allows to extend this standard

 * set by creating new instances of additional features if needed.<BR>

 * <P>

 * This class corresponds to DescriptionsSectionType according to the SDD

 * schema.
