org.apache.xerces.dom.NamedNodeMapImpl

NamedNodeMaps represent collections of Nodes that can be accessed by name. Entity and Notation nodes are stored in NamedNodeMaps attached to the DocumentType. Attributes are placed in a NamedNodeMap attached to the elem they're related too. However, because attributes require more work, such as firing mutation events, they are stored in a subclass of NamedNodeMapImpl.

Only one Node may be stored per name; attempting to store another will replace the previous value.

NOTE: The "primary" storage key is taken from the NodeName attribute of the node. The "secondary" storage key is the namespaceURI and localName, when accessed by DOM level 2 nodes. All nodes, even DOM Level 2 nodes are stored in a single Vector sorted by the primary "nodename" key.

NOTE: item()'s integer index does _not_ imply that the named nodes must be stored in an array; that's only an access method. Note too that these indices are "live"; if someone changes the map's contents, the indices associated with nodes may change.
