/**
 * This implementation of NamespaceContext has the ability to maintain multiple
 * scopes of namespace/prefix bindings.  This is useful in situations when it is
 * not always appropriate for elements to inherit the namespace bindings of their
 * ancestors (such as included elements in XInclude).
 * 
 * When searching for a URI to match a prefix, or a prefix to match a URI, it is
 * searched for in the current context, then the ancestors of the current context,
 * up to the beginning of the current scope.  Other scopes are not searched.
