revision:
The <nav> tag defines a set of navigation links. Notice that NOT all links of a document should be inside a <nav> element, which is intended only for major block of navigation links.
A document may have several "nav" elements, for example, one for site navigation and one for intra-page navigation. "aria-labelledby" can be used in such case to promote accessibility. Browsers, such as screen readers for disabled users, can use this element to determine whether to omit the initial rendering of this content.
