<anchor>

<anchor> acts as <a> does but it is associated with only one medium and it has time properties.

<anchor> is a son of a media element.. Its "begin" and "end" attributes are relative to the begining of its father.

<anchor id="identifier"
        show="replace|new|pause"
        href="URL"
	skip-content="true|false"
	coords="x1,y1,x2,y2"
	begin="clock-value"
	end="clock-value" />
