/**
 * Generate the simplest XmlElement annotation possible taking all semantic optimizations
 * into account.  This method is essentially equivalent to:
 *
 *     xew.name(ctype.getTagName().getLocalPart())
 *        .namespace(ctype.getTagName().getNamespaceURI())
 *        .type(jtype)
 *        .defaultValue(ctype.getDefaultValue());
 *
 * @param field
 * @param ctype
 * @param jtype
 * @param checkWrapper true if the method might need to generate XmlElements
