Purpose
A 
provides a standardized way to represent postcoordinated expressions. This representation is useful for the implementation of a postcoordinated expression repository.

Postcoordinated Expression Type Reference Set Examples
The International Edition of SNOMED CT includes two different types of the 
. These are the 
and 
. Both of these reference sets provide a standardized way of representing different types of SNOMED CT expressions, and are useful for the implementation of a postcoordinated expression repository.
The provides a standardized way to represent postcoordinated expressions as they were captured by the users, but in a 
. The provides a standardized way to represent postcoordinated expressions in a 
. The classifiable form is a syntactically valid and concept model compliant representation of the 
, and serves as the input to the classifier, enabling compositional expressions to be classified with SNOMED CT content.
