+ * Contains key-value pairs (elements) where keys are "displayable"

+ *
+ * <pre>{@code
+ * Set<String> keys = MAC_CATEGORY.getDisplayableKeys();
+ *
+ * String key = getLastValue(keys); // get last value for example
+ *
+ * String value = MAC_CATEGORY.getValueForDisplayableKey(key);
+ * params.put(MAC_CATEGORY.getID(), value);
