The documentation at https://v3.vuejs.org/guide/a11y-semantics.html#labels shows using aria-labelledby however with Vue Components that breaks down as id is global within the page rather than local in scope to your component. I feel the documentation could do this a more vue way allowing components to be re-used multiple times within the page while still doing aria-labelledby.

For example something like vuejs/vue#5886 (comment) works well.
