Template Syntax Specification

The SNOMED CT Template Syntax defines a standard way to create templates for SNOMED CT expressions and expression constraints. It introduces slots as placeholders for values that can be filled in later, enabling reusable patterns for authoring, validation, and data entry. This syntax supports consistent, computable use of SNOMED CT across systems and is designed for both technical and non-technical users.
