<!-- coordGeomRefs identifies one or more 'name' values that link to specific <Line>, <Curve>, <Spiral> or <IrregularLine> in a <CoordGeom> element. This allows linking an survey observation to specific <Parcel>.<CoordGeom> based geometry. -->
   
<!-- alignRef is the name of the alignment.
       alignStationName is the station value where the rod reading is taken.
       alignOffset is the signed (+
/-) distance from the CL of the referenced alignment.  -->
