Point is in model coordinates. The value is related to Position. It may have a different value than Position depending on the values of LocationSpot and LocationElementName. The value is actually stored on the VisualElement. One normally sets it by setting or data-binding the attached property on the root element of the DataTemplate.It is common to set the LocationSpot to Spot.Center, so that the location of the node is always the coordinates of the center point of the LocationElement. The Position always refers to the top-left corner point of the Bounds. Setting the Position will also update this Location.
Grid snapping, for example, will normally locate node Locations to be on grid points. (But you can change that by setting GridSnapCellSpot.) By setting the node's LocationSpot to be the center of one of the node's elements, by default the whole node, the element will be centered at the location.
The MinLocation and MaxLocation also operate on the node's location, not its position.
However, the Move method takes a position, not a location.
This attached dependency property is set by various tools and layouts. Therefore one-way data-bindings of this attached dependency property to changing source properties may not get updated values.
