In this file, the <ISINDEX> tag occurs three times. Once it
appears in the <HEAD> (it is still not allowed more than once
in there), a second time at the beginning of the <BODY>, which
you can see as the second widget at the top of the screen, and a third time further
into the <BODY> which you can see below. In HTML Level 2 (Strict or no)
the <ISINDEX> tag is allowed only once in the <HEAD>
and any number of times in the <BODY>. When used there it inserts
its widget at the point in the flow of text where the tag occurs. When this tag
occurs more than once on a page, it does not matter which one the user enters data
in, the effect is the same.
