icbaker has just created a new issue for https://github.com/w3c/ttml2: == tts:zIndex wording seems backwards == https://www.w3.org/TR/2018/REC-ttml2-20181108/#style-attribute-zIndex says (emphasis mine): > The `tts:zIndex` attribute is used to specify a style property that defines the **front-to-back** ordering of region areas in the case that they overlap. When reading this I assumed 'ordering' meant 'ascending' and therefore 'front' is 'low' and 'back' is 'high' (since it says front to back), but the example is the opposite. The example is also consistent with how I think CSS z-index works. So is the wording in the TTML spec just incorrect and should instead say: > The `tts:zIndex` attribute is used to specify a style property that defines the back-to-front ordering of region areas in the case that they overlap. And/or an explicit sentence added to help a reader wondering which order the index is defined in.
