nigelmegitt has just created a new issue for https://github.com/w3c/imsc: == `<percentage>` not defined == The new attribute `ittp:activeArea` takes 4 of `<percentage>` but this is not defined. One place it could potentially be derived from is a subset of the TTML1SE definition of [`<length>`](https://www.w3.org/TR/ttml1/#style-value-length) however that definition of `percentage` is based on `number` which permits negative values; in the case of `ittp:activeArea` negative values are prohibited. Steps to resolve: * [ ] Clarify source of definition of `<percentage>`. * [ ] If it's from TTML1SE as above then add a normative statement prohibiting negative values.
