9 * Maintains all data pertient to an XML node, including sub-nodes and content.
10 * All child nodes can be accessed through index and through name via a hash
11 * table. This makes it very easy to gain simple and fast access to all of
12 * your data. For most applications, the memory footprint is also rather
13 * small. While XmlNode objects can be used directly to create XML structures
14 * it is highly reccomended that all operations be performed through the
15 * XmlDocument class.
