Template Syntax Specification (http://snomed.org/-sts)

• Examples: 7.1. Simple Replacement Slots

• Default replacement type will be SCG (i.e. expression)

• Processing a template will require both syntactic and concept model checking to determine validity of resulting expression

• If another replacement type is needed (e.g. for DefinitionStatus) then the replacement type must be explicitly stated

• A replacement type of 'token' was suggested (instead of string) for the DefinitionStatus

• Other replacement types (e.g. str, int, dec) will be required for concrete values

• It was proposed that it should be mandatory to include either a 'name' or a 'reference' in a replacement slot

• Further discussion required on 'join operators' (e.g. "+", ",", "AND", "OR")
