속성att.global (@xml:id, @n, @xml:lang, @rend, @rendition, @xml:base, @xml:space) (att.global.linking (@corresp, @synch, @sameAs, @copyOf, @next, @prev, @exclude, @select)) (att.global.analytic (@ana)) (att.global.facs (@facs)) (att.global.change (@change))
type그래프의 유형을 기술한다.
상태 권고적
자료 유형 

<rng:ref name="data.enumerated"/>
data.enumerated
제안값은 다음을 포함한다:
undirected
무방향 그래프
directed
방향 그래프
transitionNetwork
시작과 종료 노드가 구분되는 방향 그래프
transducer
각 호에 두 개의 표지를 부착한 전이망
order그래프의 순서를 진술한다. 즉, 그래프 노드의 번호.

자료 유형 

<rng:ref name="data.count"/>
data.count
값 A positive integer.
size그래프의 크기를 진술한다. 즉, 그래프 호의 수.
