A line, whose vertices are described in the same absolute CRS as the linethat defines one edge (usually either the top or bottom edge) of the samplingfeature’s surface. Where appropriate, this unit is used to represent theintersection of a 2D surface with the ground, DEPRECTED. Only necessary with deprecated VectorLinearReferenceSystem. Instead, this element is replaced bythe x-axis definition of a LocalCartesianCRS where relative coordinates are used todefine the feature or observations/samples within it.
The 'actuate' attribute is used to communicate the desired timing of traversal from the starting resource to the ending resource; it's value should be treated as follows:onLoad - traverse to the ending resource immediately on loading the starting resource onRequest - traverse from the starting resource to the ending resource only on a post-loading event triggered for this purpose other - behavior is unconstrained; examine other markup in link for hints none - behavior is unconstrained
The 'show' attribute is used to communicate the desired presentation of the ending resource on traversal from the starting resource; it's value should be treated as follows: new - load ending resource in a new window, frame, pane, or other presentation contextreplace - load the resource in the same window, frame, pane, or other presentation contextembed - load ending resource in place of the presentation of the starting resourceother - behavior is unconstrained; examine other markup in the link for hints none - behavior is unconstrained
