30       * a given namespace URI is already declared, nothing happens.

36       * <p>
37       * For marshalling to work correctly, all namespace bindings
38       * for an element must be declared between its startElement method and
39       * its endAttributes event. Calling the same method with the same
40       * parameter between the endAttributes and the endElement returns
41       * the same prefix.

43       * @param   requirePrefix

45       *      to this namespace, even if it's already bound to the default
46       *      namespace. IOW, this method will never return null if this
47       *      flag is true. This functionality is necessary to declare
48       *      namespace URI used for attribute names.
49       * @param   preferedPrefix
50       *      If the caller has any particular preference to the
51       *      prefix, pass that as a parameter. The callee will try
52       *      to honor it. Set null if there's no particular preference.
53       * 
54       * @return
55       *      returns the assigned prefix. If the namespace is bound to
56       *      the default namespace, null is returned.
