 //  harness will not mistake this file as a test file.  It should
 //  only see the html file as a test file. (the harness runs all
 //  valid test files, so it would run this test twice if this file
 //  were valid as well as the html file.)
 // Also, note the area= after Your Name in the author tag.  Here, you
