interval endpoint status (exclusive/inclusive) marker: independent of the other, all options satisfy
Claims that the bridi is true for either option of endpoint on this side of the interval, independent of the status of the other endpoint; so, the bridi is claimed to be true for the interval specified so long as the other endpoint is as specified: the endpoint associated with this word (the not-"other" one) may be inclusive or exclusive without causing the statement to become untrue. Neither option for these statuses is "picked"; either may be substituted into the bridi and the truth value is claimed to remain the same (namely, True). The other endpoint status may be explicitly be specified to a definitive realization, but the default will be xai'u'oi or xau'u'oi. See also: xei'u'oi, xau'u'oi, xoi'u'oi.
