Allowable Ranges for Concept Model Attributes   

Attributes by domain    Historical    Without attributes   

From confluence.ihtsdotools.org (September 2017)
Some domains are not top-level hierarchies, and some top-level hierarchies are not domains. Each item in the Hierarchy column refers to the top-level hierarchy where the attribute applies. Some of these do not actually apply at the very top of the hierarchy, but are restricted to a domain defined lower down. Some of them apply to more than one top-level hierarchy. Each item in the Attribute column refers to a single attribute that resides in the Attribute hierarchy.

From confluence.ihtsdotools.org
Each attribute has a specific domain to which it applies; in many cases these domains are simply the same as the top-level hierarchies, as listed in parentheses after the domain name. In other cases, there is a more restrictive domain. In the following table, the left-hand column names the specific domain, and the right hand column the defining attributes.

(<<) this code and descendants,

(<=) descendants only (stated) except for supercategory groupers,
(==) this code only,
(< Q) descendants only when in a qualifying Relationship,
(< Q only) descendants only, and only allowed in a qualifying Relationship.
A supercategory grouper is sufficiently defined by reference to a value that is at the top of the value hierarchy, resulting in a very general meaning, such that the code is less useful (or sometimes useless) for record entry, but is useful as an organizer of the hierarchy.
