skynavga has just created a new issue for https://github.com/w3c/ttml2:

== Clarify inheritance of line height 'normal'. ==
It looks like https://github.com/w3c/ttml1/issues/220 never got listed in https://github.com/w3c/ttml2/issues/358, and we didn't catch this in review.

Note that CSS2.1 (2011) [1] already says as much, and we normatively reference CSS2.1 in TTML2 (emphasis added):

**normal**
Tells user agents to set the used value to a "reasonable" value based on the font of the element. The value has the same meaning as <number>. We recommend a used value for 'normal' between 1.0 to 1.2. _The computed value is 'normal'._
