<action type="add" issue="30">
<![CDATA[<b>API CHANGE:</b>]]> The TagList class previously implemented ArrayList semantics,
but this has been replaced with LinkedHashMap semantics. This means that the list of
tags will no longer accept duplicate tags, but that tag order will still be
preserved. Thanks to Bill de Beaubien for reporting!
