An anchor is a piece of text or
some other object (for example an image icon) which marks the beginning
and/or the end of a hypertext link or an area within a the content of
which is the source or destination of a link.
The anchor may be the whole of the node content. Typically, clicking a
mouse on an anchor area causes the link to be followed, leaving the
anchor at the opposite end of the link displayed. Anchors tend to be
highlighted in a special way (always, or when the mouse is over them),
or represented by a special symbol. An anchor may, and often does,
correspond to the whole node. (also sometimes known as "span",
"region", "button", or "extent").
