Assembly: System.Xml (in System.Xml.dll)
The XmlNameTable stores atomized strings of any local name, namespace URI, and prefix used by the XPathNavigator. This means that when the same Name is returned multiple times (like "book"), the same String object is returned for that Name. This makes it possible to write efficient code that does object comparisons on these strings, instead of expensive string comparisons.
