Class GroupActivation

GroupActivation represents one activation of a saxon:group loop. It is implemented as a NodeEnumeration with one extra method, the ability to test whether the value of a key on the current node is the same as the value of the key on the next node. Control over the iteration is shared between the saxon:group and saxon:item elements.
