Attributes:
 curveType: type of vertical curve, e.g. arc or straight (obligatory;
xs:string )
 Possible values:
 arc: curve, that link two (e.g. straight) elements of gradient profile of a railway track, with a constant radius that is not infinite
 mixed: an aggregated curve with arcs and straight parts
 straight: curve with constant infinite radius (zero curvature),
 deltaGradient: change of gradient of the gradient curve in per mille;
use this attribute if the gradient value of the gradient curve is not constant, but changing; the delta gradient shall be calculated as difference of gradient at the end and gradient at the beginning of the gradient curve (optional; xs:decimal ),
 gradient: constant gradient of the gradient curve in per mille;
positive values indicate an upward slope (rise), negative values indicate a downward slope (fall) (optional; xs:decimal ),
 length: length of the gradient curve in metres;
use this attribute in particular to define the arc length (optional; xs:decimal ),
 radius: radius of the gradient curve in metres;
use negative values to describe the arc curve of a valley and use positive values to describe the arc curve of a hill (optional; xs:decimal ),
 id: the identifier of the object; this can be either of type xs:ID or UUID (obligatory;
xs:ID ); compare: Dev:Identities

^{*}Notice: Elements may have different parent elements. As a consequence they may be used in different contexts. Please, consider this as well as a user of this wiki as when developing this documentation further. Aspects that are only relevant with respect to one of several parents should be explained exclusively in the documentation of the respective parent element.
