SoSFNode — field containing a pointer to a node

       This field maintains a pointer to an SoNode instance, correctly maintaining its reference count.

       SoSFNodes are written to file as the node they are pointing to. For example:

          mySoSFNodeField Cube {}

     is  an  SoSFNode  field named 'mySoSFNodeField', pointing to an SoCube node. If the node is used elsewhere,
     the regular DEF/USE instancing mechanism applies:

          anotherSoSFNodeField USE topSeparator

     is an SoSFNode field that points to a node named 'topSeparator' that was DEF'ed earlier in the scene.
