WorldInfo

Definition :
WorldInfo { 
  field MFString info  []
  field SFString title ""
}
Explanation :

The WorldInfo node contains information about the world. This node is strictly for documentation purposes and has no effect on the visual appearance or behaviour of the world. The title field is intended to store the name or title of the world so that browsers can present this to the user (perhaps in the window border). Any other information about the world can be stored in the info field including scene author, copyright information, and public domain information.
