BaseNode usage in SFNode

Hello,

I'm trying to see the purpose of passing the BaseNode Abstract class as a
parameter in the constructor and setValue() functions of the SFNode class(
SFNode is extended from Field class and not BaseNode in the vrml 2.0 spec).
How could BaseNode be instantiated when its an abstract class and how is
it used in the SFNode.

Thanks in advance
