Types of References
Prescriptive reference (PR):
The concept in the EDCS is the same concept as defined in an external specification. The definition of the concept in EDCS may be different from the definition in the specification because of modifications to:
- include missing (implied) context not present in the definition in the specification; or
- to match the style and structure of other definitions in the EDCS.
In this case a citation is provided in the References field.
Authoritative reference (AR):
The concept in the EDCS prescriptively references a concept from an external specification, and an agreement has been established between the owner of the EDCS and the owner of that specification to ensure that the concept authoritatively referenced is not changed without the agreement of the owner of the EDCS.
In this case, a citation is provided in the References field.
