/**
 * Delegate to the default implementations of the various interfaces
 * extended by ResourceRepository.
 *
 * This resource repository can use the SAME key to extract three different
 * types of resources from a single resource bundle:
 * 1. Strings are fetched from the resource bundle with the same
 *     key that was passed to this repository. The string will be stripped
 *     of its first ampersand.
 * 2. Mnemonics are calculated from the string fetched from the resource
 *     bundle with the same key that was passed to this repository.
 *     The mnemonic is calculated from the position of the first
 *     ampersand in the string.
