+	 * To specify the category of the message, prefix the message with the category name and separate it
+	 * with "|". For example, "app|hello world". If the category is not specified, the default category "app"
+	 * will be used. The actual message translation is done by a [[\yii\i18n\MessageSource|message source]].

+	 *
+	 * For example, if a translated message is "I have an apple.|I have {n} apples.", and the first
+	 * parameter is 2, the message returned will be "I have 2 apples.". Note that the placeholder "{n}"
