This section defines requirements for the normative representation of an HL7 V3 Template.

Template Assertions
Static assertions
- A template can constrain the cardinality of a clone’s association.
- A template can constrain the cardinality of a clone’s attribute.
- A template can constrain the allowable date/time values in a date/time field.
- A template can constrain any attribute value to be a subset of those values legally permissible in the specification being constrained.
- A template can constrain the range of allowable date/time values for attributes valued by date/time data types.
- A template can constrain the range of allowable code values for attributes valued by terminology concepts.
- A template can constrain the range of allowable numbers for attributes valued by numbers.
- A template can express a regular expression constraint on attributes valued by strings.
- A template can constrain any data type component, including recursively-nested components.
- A template can constrain the range of allowable values of a clone’s attribute.
- All additional constraints that can be expressed in a normative specification (including all the columns in an HMD) can be further constrained in a template or archetype.
