These operators use a scope based on a group. From v5.6.0 they can work with sets or lists, retaining data type, or may use expressions evaluating as lists or sets.
The group may be:
- any designator from {children,descendants,sibling,ancestor,all}
- a find() (from v5.6.0)
- a list-based group designator (from v5.6.0)
Such operators are:
- any(group,value)
- avg(group,value)
- collect(group,attribute)
- every(group,value)
- linkFrom("item"[,linkType])
- linkTo("item"[,linkType])
- sum(group, value)
- unlinkFrom(item[,linkType])
- unlinkTo("item"[,linkType])
