LC/PCC practice: In most cases, do not apply the option. However, if a single note includes descriptions of more than one aspect of a resource entity, apply the option to use Manifestation: note on manifestation.

LC/PCC practice: Apply the option when a structured description of the extent of manifestation of accompanying material is not desired, but certain details of the accompanying material are considered important for identification or selection.
