.

Different versions of a reference set member share the same

but have different

tTime

The inclusive date or time at which this version of the identified

Gloss

treference set member
became the current version.

The current version of this

If

Specref

Historical Association Rules and Guidance

Each member of a

Concept

ShowFormatinline
 reference set represents a reference from an
Gloss
Spacetrue
tinactive component
to other equivalent or related
Gloss
Spacetrue
tcomponents
that were current in the
Gloss
Spacetrue
tRelease Version
in which that
Gloss

tcomponent
was inactivated.

Each
