how to load item cross reference property table by dataloader?

For oracle xstore version 22, trying to populate itm_item_cross_reference_p table with dataloader (by mnt file), couldn't find the record type in xstorepos-220-hig.pdf for item cross reference property table (itm_item_cross_reference_p table), only ITEM_XREF record found, but that's for item cross reference table itm_item_cross_reference, not for item cross reference property table. Is there any recommendation for populating this table itm_item_cross_reference_p? thanks!
