값 Each value specified must be the same as that specified as value for an xml:id attribute for some other element in the current document.
mode이 집합에 모아진 교체가 배타적인지 또는 총괄적인지를 진술한다.
상태 권고적
적법한 값은:
excl
(배타적) 교체가 배타적임을 나타낸다. 즉, 기껏해야 교체 집합 중 하나가 나타난다.
incl
(총괄적) 교체가 배타적이 아님을 나타낸다. 즉, 교체집합 중 하나 이상이 나타난다.
weightsmode가 excl이라면, 각 가중치는 대응하는 교체가능성이 발생할 확률을 말한다. mode가 incl이라면, 각 가중치는 적어도 다른 교체가능집합 중 하나가 발생한 상태에서 대응하는 교체가능성이 발생할 확률이다.
