21 * An implementation of the Transform interface which converts all
22 * input text to either upper or lower case.
23 * <p>
24 * Note that because it doesn't use any nested tags for configuration,
25 * just xml attributes which map 1:1 onto bean property-setter methods,
26 * there is no need to define any custom addRules method to use this
27 * as a Digester plugin class.
