Left examples have the keyword "sequence" on the OEBP.
Right examples have the keyword "fixedsequence" on the OEBP.
Zero, one, or two objects may technically form a sequence, but if ALL examples of a BP have zero, one, or two objects, we do not consider that BP to be about sequences. BPs about fixed two-object sequences are ordered pairwise comparison BPs, orderedpair.
