does show in IE. Can someone explain why? Any helpful insight would
be appreciated.

The DOCTYPE is incomplete, and it should have "html" instead of "HTML".
The namespace property is spelled "xmlns", not "xmlins".
Forcing the body background color only is bad practice, because you
don't know what the user's default are. Either set all the colors or
leave them alone.
The "language" property of the "script" element is obsolete.
The MIME type for JavaScript is "text/javascript", not "text javascript".
Using <!-- ... --> is obsolete.
document.write does not work with XHTML (and isn't supposed to). Use the
DOM model.
