In addition to the standard "StepTemplate" that can display information, there are two node DataTemplates: "TransitionTemplate" and "ParallelTemplate".

The "ParallelTemplate" is drawn as a rectangular bar whose width is bound to the NodeData.Width property. To allow the user to resize that Rectangle, the `go:Part.SelectionElementName` refers to that "Bar" element. Because that data-binding is `Mode=TwoWay`, the data property is updated when the user resizes that rectangular bar.

The "ParallelTemplate" demonstrates the use of a custom Resize adornment. Instead of the standard eight resize tool handles positioned within a SpotPanel, the custom "ResizeAdornmentTemplate" uses only two tool handles, one at the middle-left, and one at the middle-right. Note that each Adornment for resizing a Node is managed by the ResizingTool and is independent of other Adornments used by other tools. Tool adornments are also independent of the Adornment used to show selection (when `go:Part.SelectionAdorned="True"`).
