A concept that is a subtype of a specified concept.
Notes
Includes the subtype children and the subtype children of each subtype child and so on recursively.
The terms subtype and subtype descendant are synonymous. However, it is sometime helpful to use the term subtype descendant to emphasize inclusion of all subtypes not just subtype children.
Example
The figure below shows an example hierarchy in which concept C has eight subtype descendants (F, G, M, N, O, P, U and V).
