On product: TTML2

Incorporate functionality such as that provided by ebutts:multiRowAlign, described in EBU Tech 3350 [1] with detail in Appendix A, to allow rendered rows of text to be aligned to each other, and for the set then to be aligned as per the existing tts:textAlign attribute. An example would be to left align each row of text displayed, with each other, and then to centre the set of rows overall. This enhances readability and is a common subtitling display practice in use today.
