-<xsd:complexType name="cs_refWellboreTrajectoryStation" final="#all">
-<xsd:annotation>
 <xsd:documentation>A reference to a trajectoryStation in a wellbore. The trajectoryStation may be defined within the context of another wellbore. This value represents a foreign key from one element to another.</xsd:documentation>
 </xsd:annotation>
-<xsd:sequence>
-<xsd:element name="stationReference" type="witsml:refString" minOccurs="1" maxOccurs="1">
-<xsd:annotation>
 <xsd:documentation>A pointer to the trajectoryStation within the parent trajectory. This is a special case where we only use a uid for the pointer. The natural identity of a station is its physical characteristics (e.g., md).</xsd:documentation>
 </xsd:annotation>
 </xsd:element>
-<xsd:element name="trajectoryParent" type="witsml:refNameString" minOccurs="1" maxOccurs="1">
-<xsd:annotation>
 <xsd:documentation>A pointer to the trajectory within the parent wellbore. This trajectory contains the trajectoryStation.</xsd:documentation>

-<xsd:element name="wellboreParent" type="witsml:refNameString" minOccurs="0" maxOccurs="1">
-<xsd:annotation>
 <xsd:documentation>A pointer to the wellbore that contains the trajectory. This is not needed unless the trajectory is outside the context of a common parent wellbore.</xsd:documentation>
