/**
 * {@link Plugin} that forces capitalization of every word composing a XML name 
 * during conversion to a java name. 
 * XJC doesn't change a composing word starting with an upper case character 
 * (e.g. an uppercase word), but unconditional capitalization can be useful 
 * for processing XML documents whose tags are all uppercase with a separator 
 * char between words (e.g. ONE_WORD, ONE-WORD,...). 
 * Someone seems to like UPPERCASE chars :-)
 *
 * Example:
 *
 * default:
 *   FIRST_NAME -> FIRSTNAME
 *   FOOBar     -> FOOBar
 *   SSNCode    -> SSNCode
 *
 * capitalizing every word:
 *   FIRST_NAME -> FirstName
 *   FOOBar     -> FooBar
 *   SSNCode    -> SsnCode
