`dataItemId`	`ID`	1.5	1	unique identifier of the `DataItem` associated with this `Observation`. `::dataItemId` MUST match the `::id` attribute of the `DataItem` defined in the MTConnectDevices Response Documentresponse document published by an MTConnect Agent in response to a probe request..
`name`	`string`	1.5	0..1	name of the `DataItem` associated with this `Observation`. `::name` MUST match the `::name` attribute of the `DataItem` defined in the MTConnectDevices Response Documentresponse document published by an MTConnect Agent in response to a probe request..
`sequence`	`integer`	1.5	1	number representing the sequential position of an occurrence of an observationobserved value of a property at a point in time. in the data buffer of an agentsoftware that collects data published from one or more piece(s) of equipment, organizes that data in a structured manner, and responds to requests for data from client software systems by providing a structured response in the form of a response document that is constructed using the semantic data model of a Standard. . `::sequence` MUST have a value represented as an unsigned 64-bit value from 1 to \(2^{64}-1\).
