Attribute Codes
- This International Standard uses environmental attributes to describe the state of objects.
- Each attribute is identified by both a unique label and a unique EDCS Attribute Code (EAC).
- The definition of each attribute includes any constraints that may apply to that attribute.
- Each attribute has a type and may have an associated unit label or formula.
- Attributes are defined in tables with codes grouped using the General organizational schema defined in Clause 8.
