NamespaceContextWrapper

public class NamespaceContextWrapper extends Object implements NamespaceContext
Writing a wrapper to re-use most of the namespace functionality already provided by NamespaceSupport, which implements NamespaceContext from XNI. It would be good if we can change the XNI NamespaceContext interface to implement the JAXP NamespaceContext interface. Note that NamespaceSupport assumes the use of symbols. Since this class can be exposed to the application, we must intern all Strings before calling NamespaceSupport methods.
