skynavga has just created a new issue for https://github.com/w3c/ttml2: == Define default value for xlink:show. == Specify a default value for `xlink:show` in ยง8.2.5, where the possible values are `new`, `replace`, `embed`, `other`, `none`. In the case of TTML, my suggestion is to use `none`, which is assigned the following semantics in [XLink 1.1]: >The behavior of an application traversing to the ending resource is unconstrained by this specification. No other markup is present to help the application determine the appropriate behavior. Alternatively, consider that SVG 1.1 restricts the value of `xlink:show` to `new` and `replace` (in similar linking contexts) and assigns a default value of `replace`. However, for TTML captions, I suspect that the default linking behavior should not replace the subtitle presentation; therefore, it seems better to make show semantics application dependent, which is accomplished by `none` (or perhaps `other`).
