[ttml1] Should tts:direction apply only to <span>?

palemieux has just created a new issue for 
https://github.com/w3c/ttml1:

== Should tts:direction apply only to <span>? ==
TTML1 specifies that `tts:direction` follows the semantics of XSL 
Section 7.29.1, which states that:

_The "writing-mode" property establishes both the 
block-progression-direction and the inline-progression-direction. The 
"direction" property only changes the inline-progression-direction and
 is used primarily for formatting objects that generate inline-areas 
that are not also reference areas. Use of the "direction" property for
 other formatting objects is deprecated in this specification._

So shouldn't `tts:direction` only apply to `span` (which generates 
inline-areas) and not to `p` (which generates block-areas)?
