This element specifies the definitive geometry of the center line of the given line object in the given CRS.
Applications should use this information in rendering the line object when ever possible.
The using applications should note, that rendering the line in other CRS (projection) that the given one
probably requires a more complex path matching than simply re-projecting the control points. One possible way
would be sampling the curve as lineString with appropriate frequency, translating the sampled lineString,
and finally fitting a new cubic spline to the sampled and translated lineString.
If only rendering (and not editing) of the line object is needed, the secondary geometry information of the
lineStringInterpolation (if given) element may suffice for drawing the line object, this depends on the
value of the samplingFrequency element and the intended visualization resolution. The lineString interpolation
is straight forward to convert to another CRS, as the conversion can be done point by point.

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 context
replace - load the resource in the same window, frame, pane, or
other presentation context
embed - load ending resource in place of the presentation of the
starting resource
other - behavior is unconstrained; examine other markup in the
link for hints
none - behavior is unconstrained

Abstract parent type for WOML Objects defined line segments
between an ordered set of geospatial points.
The points defined in each of the given line segments
should be considered as one consecutive array of geospatial points. If there are more
that one segment, the first point (in the orientation order) of each of the segments
following the first one is ignored (the first and the last point coordinates
must always represent the same point).
The orientation of the line is defined by attribute "orientation", starting from the first position
in the position list and ending to the last position if positive.
This may or may not affect the semantics and the rendering of the line object
(depending on whether the concrete types have a natural direction or not).
If elevation
property is given, its value must be added to possible height value of each of the
points in the each line segment. If the CRS of the points is 2-dimensional, the
value of the elevation should be interpreted as the static height value of each of
the given (control)points.
Database handle for the object. It is of XML type ID, so is constrained to be unique in the XML document within which it
occurs. An external identifier for the object in the form of a URI may be constructed using standard XML and XPointer methods.
This is done by concatenating the URI for the document, a fragment separator, and the value of the id attribute.
