OptionalslotThe model slot the file's nodes belong to (#4444). Every node path, and
every children / inherits reference, is qualified with the slot's
prefix, and the file's header / imports / schemas are recorded for that
slot (see slot-ifcx.ts). Omitted: the implicit legacy slot (paths and
room-wide metadata untouched).
Origin tag for the seeding transaction. Defaults to SEED_ORIGIN.
