-  <description>
-    <p>
-      The Chewing input method is designed for entering Traditional Chinese text.
-      Chewing helps you inputting Traditional Chinese by its pronunciation, in the
-      form of either Bopomofo/Zhuyin or Hanyu pinyin, as well as Chinese punctuation
-      marks and normal and full shape number and English alphabets.
-    </p>
-    <p>
-      Input methods are typing systems allowing users to input complex languages.
-      They are necessary because these contain too many characters to simply be laid
-      out on a traditional keyboard.
