Variants, and Modified Concepts. It includes displayable text, distinguishing text (that portion of text that makes a modified
concept different from the parent concept) and the term definitions (when available). Searches are conducted using the special

individual designations (terms) belong to the concept each have their own codes (designation
identifiers).
