Gets and sets the vertical coordinate system wkid
to be used to select the target spatial reference for the
TransformationInfo object (used to populate a table row).
The TargetVcsWkid is optional. The default is 0. The TargetWkid should also be defined if a TargetVcsWkid is defined. If the TargetWkid and the TargetVcsWkid are set, then the corresponding TargetSpatialReference with that wkid and vcsWkid will be selected for the TransformationInfo object. Note: only one of: o TargetSpatialReference o TargetWkid, and TargetVcsWkid if applicable o TargetWkt, and TargetVcsWkt if applicable need be set. If the TargetSpatialReference is set, Wkids and Wkts are ignored. If the TargetSpatialReference is null, then Wkids are used. If the Wkids are 0 (or less), then the Wkts are used.
