Purpose

A

Concept
t900000000000506000|Language type reference set|
supports the representation of
Gloss
tlanguage
and
Gloss
tdialects
preferences for the use of particular
Gloss
tdescriptions
. The most common use case for this type of
Gloss
treference set
is to specify the acceptable and preferred terms for use within a particular country or region. However, the same type of
Gloss
treference set
can also be used to represent preferences for use of
Gloss
tdescriptions
in a more specific context such as a clinical specialty, organization or department.
