LXML: can't register namespace

[Andrew Z]

help(etree.register_namespace)
Help on cython_function_or_method in module lxml.etree:
register_namespace(prefix, uri)
    Registers a namespace prefix that newly created Elements in that
    namespace will use.  The registry is global, and any existing
    mapping for either the given prefix or the namespace URI will be
    removed.
