[imsc] Ambiguous recommendation on line height usage

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

== Ambiguous recommendation on line height usage ==
Section 7.4 states:

#lineHeight     permitted       <length> should be explicitly 
specified as there is no uniform implementation of the "normal" value 
at the time of this writing.

This language is ambiguous regarding "explicitly specified" since it 
can be specified on p, div, body, style and result in an explicit 
value being assigned to the specified style set that applies to a p. 
Probably best to rephrase as:

should be explicitly specified such that the specified style set of 
each p elements contains a tts:lineHeight property the value of which 
is not assigned by initial value fallback
