* The selectors consist of an accessible name to query for and optionally

* further aria attributes on the form `[<attribute>=<value>]`.
|
|
* Currently, we only support the `name` and `role` attribute.
|
|
* The following examples showcase how the syntax works wrt. querying:
|
|
*
|
|
* - 'title[role="heading"]' queries for elements with name 'title' and role 'heading'.
|
|
* - '[role="image"]' queries for elements with role 'image' and any name.
|
|
* - 'label' queries for elements with name 'label' and any role.
|
|
* - '[name=""][role="button"]' queries for elements with no name and role 'button'.
