palemieux has just created a new issue for https://github.com/w3c/ttml2:

== Specify implicit duration of <br>  ==
Even though no timing vocabulary applies to the `<br/>` element (see https://github.com/w3c/ttml1/issues/310). timing semantics, including an implicit duration, needs to be defined for the  `<br/>` element, otherwise the  `<br/>` element  is never displayed in the following example:

```
<p>
<span begin="1s"><br/></span>
</p>
```

whereas "hello" is displayed in the following example:

```
<p>
<span begin="1s">hello</span>
</p>
```

Suggest specifying that `<br/>` follow the same semantics as anonymous spans since `<br/>` is expected to behave like an EOL.
