spoeschel has just created a new issue for https://github.com/w3c/ttml2:
== Property specified more than once on tt:initial ==
The same property could be specified more than once on different `tt:initial` elements at the moment, e.g.:
```xml
...
<head>
<styling>
<initial tts:color="yellow"/>
<initial tts:color="lime"/>
<styling>
<head>
...
```
The [Specified Style Set Processing in 10.5.4.2](https://w3c.github.io/ttml2/#semantics-style-resolution-processing-sss) in step 6.c....i currently says:
"if an initial element defines the initial value for P, then use that value"
So the expected behaviour in such a case should probably be deterministic. Or instead it should be forbidden that at the same time two `tt:initial` elements that set the same property can apply (e.g. with appropriate conditions added, which exclude each other, the above example would be fine).
