Class NamedNodeMap
XML DOM NamedNodeMap class.
Index is kept in array part of the object, names in a separate table.
Note: the item method returns based on 1-indexed!
Use the methods only to change, to keep the two in-sync. For faster iteration use the Lua-array.
This class is used for the attributes property of an Element node. As well
as for 'entities' and 'notations' properties on the DocumentType node.
See the NamedNodeMap interface.
