+ * This is an extension of the IInputValidator interface which caters for
+ * validation of local files and URLs.
+ * <p>
+ * While isValid() is invoked dynamically as the user types his input (as per
+ * the standard IInputValidator interface), the methods
+ * <code>isFileReadable()</code> and <code>isUrlResourceReadable</code> defined
+ * by this interface are invoked when the user presses the dialog's OK button,
+ * as these operations may take longer to execute.
+ * <p>
+ * The third method, <code>isUrl()</code>, is a utility method that determines
+ * whether a given String is a URL or a simple file path.
