public class NamespaceConstant
extends Object

This class is not instantiated, it exists to hold a set of constants representing known namespaces. For each of these, there is a constant for the namespace URI and for many of them, there is a numeric constant used as the code for this namespace in the name pool.

This class also defines constant URIs for some objects other than namespaces - for example, URIs that identify the various object models used in the JAXP XPath API, and the Unicode codepoint collation URI.
