+ *
+ * - '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'.
