Gets and sets the target spatial reference wkid to be used to select the TargetSpatialReference for the
TransformationInfo object (used to populate a table row).
The TargetWkid is optional. The default is 0. The TargetVcsWkid should also be defined if a vertical coordinate system needs to be selected. If the TargetWkid (and the TargetVcsWkid if applicable) is 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.
