ARIA breadcrumbs

Accessible Breadcrumbs Markup format uses ARIA's navigation role and aria-label (role="navigation" aria-label="breadcrumbs"). E.g. HTML5 example:

<nav role="navigation" aria-label="breadcrumbs">
  <a href="/">Home</a>
  <span aria-hidden="true"></span>
  <a href="/library">Library</a>
  <span aria-hidden="true"></span>
  <a href="">Data</a>
