You are (I take it) talking applications, while I'm just talking  
definitions, where the idea of how many roots a tree *should* have  
makes no sense.  Like many mathematical concepts, there are several  
reasonable ways to define a tree; on some, every tree has a single  
root; on others some trees do not.  Whether or not a definition that  
permits more than one root suits your purposes is up to you to decide.    (02)
