     If you need to delete all attributes with a certain name you
     will have to pass an empty string as the attribute value.

    <span class="simpara">
     Only the attributes &#039;Title&#039;, &#039;Description&#039; and &#039;Keyword&#039; will
     properly handle the language prefix. If those attributes don&#039;t carry
     a language prefix, the prefix &#039;xx&#039; will be assigned.

   <blockquote><p><b class="note">Note</b>: 
    <span class="simpara">
     The &#039;Name&#039; attribute is somewhat special. In some cases it cannot
     be complete removed. You will get an error message &#039;Change of base
     attribute&#039; (not clear when this happens). Therefore you will always
     have to add a new Name first and than remove the old one.
