Yes. What is called 'valence electron' in LAPW contains 'chemical'  
valence electrons as well as 'semi-core states', and the latter can be  
deep in energy. You define the range of valence electrons by the  
separation energy in lstart, and this is typically -6 to -9 Ry (or up  
to about 120 eV) below the Fermi energy.
