The spec suggests that the “legal” links (copyright, contact, freedom
of information, privacy policies, etc.) that are often tucked away in the
footer should not be wrapped in a <nav>: “It is common for footers to
have a short list of links to various pages of a site, such as the terms
of service, the home page, and a copyright page. The footer element
alone is sufficient for such cases, without a nav element.”
We disagree with this suggestion. Many sites also include a link to
accessibility information that gives information such as how to request
information in alternate formats, and people who require such information
are those who would benefi t the most from user agents that
can take them directly to elements marked up as <nav>.
To be machine-readable, dates must be in the format YYYY-MM-DD and may also include a time, prefi xed
with “T” to separate the date and time, in the format HH:MM. Optionally you can append seconds (separated
from the minutes with a colon). Fractions of a second are allowed after a full stop mark.
As you’ve seen above, you can give a time on the 24-hour clock with no date information.
If you’re giving time and date together, you need to show the time zone: that’s either “Z” for Coordinated
Universal Time (UTC), or an offset from UTC in hours and minutes, prefi xed with a plus or minus.
Putting that all together: “1979-10-14T12:00:00.001-04:00” represents one millisecond after noon on
October 14th, 1979, in Eastern Standard Time during daylight saving time (UTC—4 hours).
If you have <footer> at the bottom and you’ll use the same info at the top, you may also use <footer> at the top.
<blockquote><footer>Ananias <cite> Scene 4.3, <a href=”http://”> The Alchemist </a></cite> (Ben Jonson) </footer></blockquote>
A <section> generally begins with a heading that introduces it. An exception to this might be a <section> that will have a heading injected using JavaScript. If you wouldn’t use a heading, or you want some wrapping element purely for styling purposes you probably should be using a <div>.
