| `FillcolorWithTransparency of color_with_transparency

Sets the fill color (used when `Style filled) with a transparency component. Default value is fully opaque lightgrey.

| `Fixedsize of bool

If true, forces the given dimensions to be the actual ones. Default value is false.

| `Z of float

z coordinate for VRML output.

]

Attributes of nodes. They include all common node attributes and several specific ones. All attributes described in the "dot User's Manual, February 4, 2002" are handled, excepted: bottomlabel, group, shapefile and toplabel.
