Why a conditionally present property row is implemented.

Metadata describes effective rows that are already present. These values retain the conformance reason; they are not predicates evaluated at runtime.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Commandable

The row is present because the object is commandable.

IntrinsicReportingRequired

The object reports intrinsically, and its table’s footnotes make this row required of such an object: the event configuration, Event_Enable, Acked_Transitions, Notify_Type, Event_Time_Stamps and Event_Detection_Enable, for example.

IntrinsicReportingOptional

The object reports intrinsically, and its table’s footnotes only let this row be present for such an object without requiring it: Event_Message_Texts, Event_Message_Texts_Config, the Event_Algorithm_Inhibit pair and Time_Delay_Normal.

AuditReporting

Audit Reporting is active, making its recipient required and writable.

ObjectAuditReporting

An optional object-owned Audit setting is provisioned.

CommandableAuditReporting

An optional Audit priority filter on a commandable reporting object.

ValueSourceTracking

The Value_Source mechanism is implemented, making its source required: on a commandable object, or on one whose noncommandable Present_Value tracks its last writer (#1552).

CommandableValueSourceTracking

Source tracking on a commandable object requires its source array and time.

PairedText

The paired Active_Text and Inactive_Text option is implemented.

LightingTrims

A Lighting Output has a trim, which makes its Trim_Fade_Time required (Addendum 135-2020ca part 5, #1528).

LightingColor

A lighting output takes its colour from a colour object, which makes Color_Reference required, and Color_Override and Override_Color_Reference too where it supports colour override (Addendum 135-2020ca part 4, #1527).
