localizedString
A localized representation for this display statement.
For example:
compact: Appearance can be modified
descriptive: For example, "Appearance of the text and page layout can be modified according to the capabilities of the reading system (font family and font size, spaces between paragraphs, sentences, words, and letters, as well as color of background and text)
Some statements contain HTTP links; so we use an `NSAttributedString`.
Parameters
descriptive
When true, will return the long descriptive statement.
