--[[
To satisfy Wikipedia:Manual of Style/Titles, certain types of items are italicised,
and others are quoted.
This submodule lists the entity-ids used in 'instance of' (P31),
which allows a module to identify the values that should be formatted.
The table p.formats is indexed by entity-id, and contains the value " or ''
