In languages in which third-person personal pronouns and demonstrative pronouns constitute separate word (sub)classes, demonstrative pronouns may substitute personal pronouns in non-subject (oblique) position.
PP=Dem: Third-person personal pronouns are not distinguished from demonstrative pronouns.
PPNonDemNonSubj: Third-person personal pronouns exist and they cannot be substituted in non-subject position by demonstrative pronouns.
PP~DemNonSubj: Although third-person personal pronouns exist, they can always be substituted in non-subject position by demonstrative pronouns.
SgPP~DemNonSubj: Although third-person pronouns exist, they can be substituted in non-subject position by singular demonstrative pronouns.
NonSgPP~DemNonSubj: Although third-person pronouns exist, they can be substituted in non-subject position by non-singular demonstrative pronouns.
PPNonAnim~DemNonSubj: Facultative use of demonstrative pronouns in non-subject position is permitted for nonhuman or nonliving entities, but only personal pronouns can be used for human or living entities.
When a language displays more than one type of marking, two values can be listed. If one type is dominant, a slash (/) can separate the two values, with the dominant value appearing first; if neither is dominant, the two are listed with an ampersand (&) separating the two.
 The same value must also be present for the parameters Demonstrative and personal pronouns in subject position and Etymology of demonstrative and personal pronouns.
 This should be explained in the commentary.
