Attributes: azimuth: constant azimuth (direction angle) of the horizontal curve in degrees; Direction "north" has an azimuth of 0 degrees, "east" 90, "south" 180 and "west" 270 degrees. (optional; xs:decimal), curveType: type of the horizontal curve, e.g. arc or clothoide or straight (obligatory; xs:string; patterns: other:\w{2,}; consider Use of tOtherEnumerationValue too.) Possible values: arc: An arc has a constant radius that is not infinite and not zero. clothoide: a curve whose curvature changes linearly with its curve length [Wikipedia] cosinusoide: Curve representing the trigonometric function cosine cubicParabola: curve based on a cubic formula (y = ax^3 + bx^3 + c) curveBloss: S-shaped transition curve curveWiener: A patented type of curve that combines the 2d aspects with the 3d parts (elevation) doucine: in France a short non-linear transition applied at the ends, smoothing the curvature variation [Bloss transition - a short design guide Constantin Ciobanu] sinusoide: a curve description based on the sinus function straight: A straight curve has a constant radius that is infinite., deltaAzimuth: change of azimuth of the horizontal curve in degrees; use this attribute if the azimuth of the horizontal curve is not constant, but changing; delta azimuth shall be calculated as difference of azimuth value at the end and the azimuth value at the beginning of the horizontal curve. (optional; xs:decimal), length: length of the horizontal curve in metres; for arcs and transition curves (e.g. clothoides) this attribute defines the arc length (optional; xs:decimal), radius: radius of the horizontal curve in meters; use value "0" (zero) to describe straight curves with infinite radius; use negative values to describe a horizontal curve going to the left (as seen from begin of curve) and use positive values to describe a horizontal curve going to the right (as seen from begin of curve) (optional; xs:decimal), id: the identifier of the object; this can be either of type xs:ID or UUID (obligatory; xs:string; patterns: (urn:uuid:)?[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}|\{[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}\}); 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.
