The RelativeVerticalPosition and VerticalAlignment properties define the boundary at which the anchor is positioned; the VerticalOffset property defines an additional amount of space to be added by which to offset the position. For example, if an anchor is top-aligned with the margin, and the offset is set to 72 pts., the object will appear one inch down from the top edge of the margin.
The unit of measurement used to express the property value is defined by the Unit property of the associated WordDocumentWriter.
