Examples of client.net.sf.saxon.ce.event.SequenceReceiver

client.net.sf.saxon.ce.event.SequenceReceiver
SequenceReceiver: this extension of the Receiver interface is used when processing a sequence constructor. It differs from the Receiver in allowing items (atomic values or nodes) to be added to the sequence, not just tree-building events.
