Using &lt;menu/&gt; would surely be a terrible idea. It would leave stray &lt;li/&gt;s all over the page for older browsers (&lt;menu/&gt; is backwards compatible in its use of list-items, but wouldn't be in this seemingly misguided (imo) use case). The spec. appears to define &lt;menu/&gt; for use within webpages, not outside for OS-level stuff.

That's not all that blogpost seems misinformed about - meta-tags are a perfectly legitimate, standardised way of adding *meta-data* to be parsed for use *outside* of the webpage (which is precisely what's being done here).
