-     This module is contained in two parts, labeled Section 'A' and 'B':
-
-       Section A declares parameter entities to support namespace-
-       qualified names, namespace declarations, and name prefixing

-    
-       Section B declares parameter entities used to provide

-
-     This module is derived from the XHTML Qualified Names Template module.
