I have noticed that the vendors often use <mtable> for visual line breaks or alignment of equations. While the visual result is often fine, it leads to excessive verbosity when read by TTS. Example:
is read out "Two lines, line one, the sum [...]". This can quickly become annoying when there are many big equations in a book.
Are there better ways to deal with visual line breaks and/or alignment? If we decide to advice against this, it would be good if the Kvalidator could check for it.
