Does a Nested Sets tree require a single root node?

It seems to me that a nested sets tree must have a single root node.  Is
this true?



I am converting an Adjacency List hierarchy to Nested Sets.  In a situation
where I am organizing a list of manufacturers into a tree, there is no
single root manufacturer - so I would have to create an "artificial" root
node called "All Manufacturers", correct?
