		<xs:documentation>Superelevation - The superelevation rate should be steep enough to provide adequate drainage of the roadway surface, but not so steep as to cause vehicles to slide down the cross slope. To prevent vehicles from leaving the roadway as they travel around curve, curves are banked, or superelevated. One edge of the pavement is constructed higher than the other edge, so that the road surface slopes toward the inside of the curve. Superelevation is expressed as a decimal value or as a percentage, and is the amount of elevation difference per unit of horizontal unit of roadway width. A 6 meter wide road with a difference in elevation between pavement edges of 0.3 m has a superelevation of 0.05, or 5%.

	<!-- Pavement Type - This element determines the pavement type. Pavements are categorized as high, intermediate, and low. High-type pavements are smoother and more stable than lower types and have good skid resistance, which is important for braking and turning maneuvers. These qualities withstand heavy traffic volumes and all weather. Intermediate-type pavements also retain their good skid resistance and smooth riding properties in all weather, but they are designed for lighter traffic loads and volumes. Low-type pavements can be surface-treated earth or other stabilized materials, or loose aggregate. Low-type surfaces do not hold their shape or drain as well as higher types, and they tend to ravel at the edges, which can affect steering. The enumeration values are: high-type, intermediate-type and low-type.  -->

The “equilibriumConstant” is a unitless optional double that is used as the equilibrium constant in the cant equilibrium equation (cant = constant * speed * speed / radius).
The “appliedCantConstant” is a unitless optional double that is used as the applied cant constant in the cant equilibrium equation (cant = constant * speed * speed / radius).
The “gauge” is a required double that is the rail to rail distance.  This value is expressed in meters or feet depending upon the units.
The “rotationPoint” is an optional string that defines the rotation point.  Valid values are “insideRail”, “outsideRail”, “center”, “leftRail” and “rightRail”.

The “rateOfChangeOfAppliedCantOverLength” is an optional double that is the rate of change of applied cant as a function of length.  This value is in millimeters /meters or inches/feet depending upon the units.
The “rateOfChangeOfCantDeficiencyOverTime” is an optional double that is the rate of change of cant deficiency as a function of time.  This value is in millimeters /seconds or inches/seconds depending upon the units.
The “cantGradient” is an optional double that is the cant gradient.  This value is unitless.
The “speed” is an optional double that is the design speed.  This value is in kmph or mph depending upon the units.
The “transitionType” is an optional enumerated type.
The “curvature” is a required enumerated type.
The “adverse” is an optional Boolean that indicates whether the cant is adverse.
