The document describes various argument types and their relationships within a structured framework for concept identification and classification. It details operations like memberof, descendantof, ancestorof, and their respective qualifiers, which help in querying and analyzing concepts in a reference set. Additionally, it addresses how to manage attributes and constraints while retrieving and processing concepts within the specified hierarchy.

1. Argument Description
• conceptId An SCTID optionally including a term surrounded by | symbols.
307082005 | Ability to process information |
• arg An expression or conceptId. Bracketting may be required to avoid ambiguity.

MemberOf conceptId
^ conceptId
The referencedComponents that are active members of
the Reference Set identified by the conceptId.
This may include both active and inactive concepts, but
will not include concepts that were once members of the
Reference Set but are no longer.
