This is a feature request. It would be really cool if we had support for Vue templates here, which requires writing an additional plugin similar to [stylelint-no-unused-selectors-plugin-jsx](https://github.com/nodaguti/stylelint-no-unused-selectors/tree/master/src/plugins/stylelint-no-unused-selectors-plugin-jsx). Currently the [documentation on plugins for stylelint-no-unused-selectors](https://github.com/nodaguti/stylelint-no-unused-selectors#writing-a-new-plugin) is kind of empty. This would probable be the first thing that needs to be tackled.
