set:difference() returns the difference between two node-sets. In other words, it returns a node-set whose nodes are in one node-set but not in the other.
The template version of
set:difference applies templates to these nodes in
set:difference mode, copying the nodes so that a result tree fragment consisting of the nodes is returned.
- The node-set from which to subtract nodes.
