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

== tts:extent, region and the style element ==
The current text in https://www.w3.org/TR/ttml-imsc1.1/#text-extent-region says:
> The tts:extent attribute SHALL be present on all region elements, where it SHALL use px units, percentage values, or root container relative units.

This forbids the following syntax:
```
<region xml:id="Region_00">
<style tts:textAlign="center"/>
<style tts:displayAlign="after"/>
<style tts:origin="10.00% 79.34%"/>
<style tts:extent="80.00% 10.66%"/>
</region>
```
And only for `tts:extent` not for `tts:origin` or others.
