More secrets: It hardly ever matters, since the content of <nav> is
normally block elements anyway – but admittedly there may be specialized
software, like speech browsers, that actually utilize the idea of <nav>
and e.g. let the user skip navigation even when the page has no
constructs for that.

Additional secret: If you assign styles to <nav>, things are different.
Old versions of IE ignore such settings, and you need something like
document.createElement('nav') in JavaScript to handle that.

Bottom line: <nav> is useless for most practical purposes. It is
harmless unless you rely on it. If you want to have some styling for the
<nav> element, either use the JavaScript trick or set the style on a
<div> element wrapped in or wrapping the <nav> element.
