Actually I thought that if a particular Tag is not registered via the Scanner 
then it will be parsed as just a Node (not of any specific type that is). But I 
guess its going to get parsed as a Tag then there is no problem. But I just 
wanted to know that what is the design consideration for not having visitNode() 
since Node is superclass of Tag.
