https://github.com/w3c/ttml2:

== Default play rate. ==
In N.2 appears:

<pre>
playRate ∈ ℜ, −∞ < playRate < ∞, playRate is unit-less, and where the 
value of
playRate is determined by the document processing context;
</pre>

This should be enhanced by adding:

<pre>
, or the value 1.0 if so determined
<pre>
