I've now revised the [explanatory spec for WebVMT](http://w3c.github.io/sdw/proposals/geotagging/webvmt/) to move the `div-id` and `tile-url` parameters to <track> element attributes, and successfully implemented these changes in the tech demo to verify the new design. This highlights another inferred step in the user agent development process, which precedes steps 1 and 2, listed above by @tidoust: 0. User agent support for WebVMT can be implemented in Javascript, using the <track> element as described in the spec, without requiring any change to the agent itself. The modified track element doesn't cause a problem as HTML handles errors gracefully and the unknown attributes should be simply ignored by the parser, allowing the WebVMT format to be used with immediate effect. Steps 1 and 2 can occur in either order, as each must define an interface (cue or map respectively) which can be incorporated into the existing solution from step 0. Hence, step 2 is linked to WebVMT development, though not in a way that obstructs its progress, and should be considered as a separate issue. Thanks to @cmheazel for moving his comments to a separate discussion in [issue #1020](https://github.com/w3c/sdw/issues/1020) If there are no further queries on this issue, I will close it. -- GitHub Notification of comment by rjksmith Please view or discuss this issue at https://github.com/w3c/sdw/issues/1019#issuecomment-388420359 using your GitHub account
