Class NamespaceConstant

java.lang.Object
net.sf.saxon.lib.NamespaceConstant
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.
