net.sf.saxon.tree.ParentNodeImpl
net.sf.saxon.tree.ElementImpl
ElementImpl implements an element with no attributes or namespace declarations.
This class is an implementation of NodeInfo. For elements with attributes or namespace declarations, class ElementWithAttributes is used.

owner
- The element owning these namespace nodes.list
- a List containing NamespaceImpl objects representing the namespaces
in scope for this element; the method appends nodes to this List, which should
initially be empty. Note that the returned list will never contain the XML namespace
(to get this, the NamespaceEnumeration class adds it itself). The list WILL include
an entry for the undeclaration xmlns=""; again it is the job of NamespaceEnumeration
to ignore this, since it doesn't represent a true namespace node.addXML
