All Implemented Interfaces:

Result, Receiver

public class SequenceNormalizer
extends ProxyReceiver

Implement the "sequence normalization" logic as defined in the XSLT 3.0/XQuery 3.0 serialization spec.

This class is used only if an ItemSeparator is specified. In the absence of an ItemSeparator, the insertion of a single space performed by the ComplexContentOutputter serves the purpose.
