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

== Clarification: Which mix of timing syntax is NOT recommended ==
IMSC1 recommends using one syntax for timing ([Section 6.11, Common Constraints, Features, #timing](https://www.w3.org/TR/ttml-imsc1/#common-features)) 

> All time expressions within a Document Instance should use the same syntax, either clock-time or offset-time.


Does this mean that "f" and "ms" approach can be mixed? Both can be offset time. In other words: Is the current syntax **not** recommended or is this not in scope of the constraint cited above:

```xml
<p begin="80ms" end="50f">..</p>
```
