etaIsoLineType

A position along the span, given by the relative coordinate η (<eta>), which runs from 0 to 1. It describes the line of all points of the chord surface with this η.

The <referenceUID> selects the coordinates: it references either a segment of the wing, and the values are then the coordinates of that segment (wingSegmentType), or a component segment, and the values are then the coordinates of the component segment (componentSegmentType).

Where the element that uses this type says so, the <referenceUID> may also reference a curve, e.g. a spar; η is then measured along that curve (see wingSparType).

Name	Type	Use	Description
`@externalDataDirectory`	`xsd:string`	optional	Directory of the external file the element was read from, as URI
`@externalDataNodePath`	`xsd:string`	optional	Path of the parent element in the merged dataset, at which the element was inserted from an external file
`@externalFileName`	`xsd:string`	optional	Name of the external file the element was read from
