The serializer now has support for DOM Level 3 serialization
(LSSerializer)
for an XML parser. These changes are seen in the new class
org.apache.xml.serializer.DOM3Serializer
and the new package
org.apache.xml.serializer.dom3
as well as a new method,
asDOM3Serializer()
on the older
org.apache.xml.serializer.Serializer
interface.
More details are in the javadoc of those classes and interfaces
