45. Type relationship tables of compound intervals

The following tables describe how compound intervals are formed from different interval types.

45.1 Match × Match

Match A Attributes	Match A_B Attributes
`id`	`new id`
`parentId` (optional)	`null`
`startTime`	Calculated based on union or intersection
`endTime`	Calculated based on union or intersection
`actorId`	From A
`relatedIntervals → relatedIntervalId`	References to A and B
`label`	User input name
`structName`	User input name
`actorAssignment`	Merge A and B uniquely by `recordingId`

Match Attributes	Watcher/Checker Attributes	Match A_B Attributes
`structName`	`structName`	User input name
`relatedIntervals → relatedIntervalId`		References to the Match and the Watcher
`parentId` (optional)		`null`
`id`		`new id`
	`issueId`	N/A
	`watcherName`	N/A
`Type`		`Match`
`childCoverageGroups`		Keep all from both intervals
`actorId`		From the Match
`label`	`label`	User input name
`actorAssignment`		From the Match
`startTime`		Calculated based on union or intersection
`endTime`		Calculated based on union or intersection
