       my %available_texts;       
   
       # <translated> starts a block of a resource that has multiple translations.
       # See the <lang> tag as well.
       # When </translated> is encountered if there is a translation for the 
       # currently preferred language, that is rendered inthe web/tex/webgrade
       # targets.  Otherwise, the default text is rendered.
       #
       # Note that <lang> is only registered for the duration of the 
       #  <translated>...</translated> block 
       #
       # Pathalogical case handling:
       #   - If there is no <lang> that specifies a 'default' and there is no
       #     translation that matches a preferred language, nothing is rendered.
       #   - Nested <translated>...</translated> might be linguistically supported by
       #     XML due to the stack nature of tag registration(?) however the rendered
       #     output will be incorrect because there is only one %available_texts
       #     has and end_translated clears it.
       #   - Material outside of a <lang>...</lang> block within the
       #     <translated>...<translated> block won't render either e.g.:
       #    <translated>
       #      The following will be in your preferred langauge:
       #      <lang which='en'>
       #         This section in english
       #      </lang>
       #      <lang which='sgeiso'>
       #         Hier es ist auf Deutsch.
       #      </lang>
       #      <lang which='sfriso'>
       #         En Francais
       #      </lang>
       #    </translated>
       #
       #    The introductory text prior to the first <lang> tag is not rendered.
