Yes, you can drop it if N does not exist

Dear all ALPS users,
I have following questions to the DMRG tutorials. Why there is N in a line: 'CONSERVED_QUANTUMNUMBERS' : 'N,Sz',
I understand that Sz stands for conserved quantum number but spin model on the open chain lattice does not have quantum number called N.
Is this N added to 'CONSERVED_QUANTUMNUMBERS' just in case someone may use some bosonic model?
Bests, Rafał
