21   * <p>A name mapper which converts types to a decapitalized String.</p>
22   *
23   * <p>This conversion decapitalizes in the standard java beans way 
24   * (as per <code>java.beans.Introspector</code>).
25   * This means that the first letter only will be decapitalized except 
26   * for the case where the first and second characters are both upper case.
27   * When both are upper case, then the name will be left alown.</p>
28   * 
29   * <p>So a bean type of <code>Foo</code> will be converted to the element name <code>"foo"</code.
30   * <code>FooBar</code> will be converted to <code>"fooBar"</code>.
31   * But <code>URL</code> will remain as <code>"URL"</code>.</p>
