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