1.42 - January 3, 2008
    - When transforming elements with attributes into hash-refs - make
    sure they are placed in the correct namespace. Previously
    <media:description> over-rided the plain <description>. (as in \ 
Flickr).

1.41 - December 4, 2008
    - Made the default keys for the channel link, description and title undef
    instead of ''. They become '' once they are opened.
        - http://rt.cpan.org/Public/Bug/Display.html?id=40686
    - Now keeping track of rdf:resource of <image> in RSS 1.0:
        - http://rt.cpan.org/Ticket/Display.html?id=3978
    - Made sure that channel/{link,description,title} are localized to
    the empty string before rendering, to allow for better backwards
    compatibility.
