Wall base definition

The definition for "hard surface flooring - includes vinyl, linoleum, laminate flooring, wood flooring, rubber flooring, wall base, and associated sundries." (LEED Reference Guide, pg.492) This suggests that all wall base product types; rubber, vinyl, wood, tile, etc. that is a wall base should follow Floorscore requirements. But when you are in the LO form the Table L-5, the product type drop down menu only gives you option for 'rubber wall base'. The drop down menu does not give you the option to specify other wall base types. Does this mean that 'rubber wall base' is the only wall base type to be considered for this requirement? Clarification on the hard surface flooring definition would be great. thanks so much.
