Some end tags are omissible, some are not. The omissibility is indicated
in the <!ELEMENT> declaration the use of the letter "O" in an appropriate
place. In XML, and hence in XHTML, end tags are never omissible.

The tags </p> and </body> (as well as the following </html>) can be
omitted in "classic" (pre-XHTML) HTML. But why do you ask? It's always
been a good practice to include them, and the gain in file size achieved
by omitting them is _really_ small.

By the way, note that first link, though valid, does not conform to
specifications, since it uses the view-source: (pseudo-)URL, which has not
been included into any published specification.

On the other hand, the entire paragraph is worse than useless, see
(replacing the icon by equivalent text does not really make things much
