Keep in mind that whatever the name, this lichanism creates a subgraph
that is not used in or attached to any scene. It is sort of floating
out in space somewhere, waiting for someone to reference it by name.
Rather than introduce these "ghosts," why not create a node whose
responsibility is to define subgraphs without having them affect
rendering. For example:
Definitions {
DEF Car Separator { <stuff > }
DEF Boat Separator { <other stuff> }
...
}
(You might notice that this is a lot a Switch node with a different
name.)
