I fixed the equals sign and now that code is error free.

I also attempted to make a couple of changes to my HTML code.  I tried to
add the following lines of code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

Then I saved my code just like you asked me to.  Finally I held down the
control button and pressed the letter r.  Everything refreshed as you
stated it should.  But the doctype code disappeared.  And once again I got
this when I ran the html code:

Why would I get this if my code now looks like this:

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="
http://www.TedTheSpeedlearner.com SVG_Ellipse_Webpage_XML_Schema.xsd">
    <head>
        <title>SVG Ellipse</title>
        <link rel="stylesheet" type="text/css" href="
http://localhost:8080/exist/rest/db/apps/HTML_Student/SVG_Ellipse.css"/>
        <script language="javascript" src="
http://localhost:8080/exist/rest/db/apps/HTML_Student/SVG_Ellipse.js"/>
    </head>
    <body onload="Setup()">
        <svg id="Image_Box">
            <ellipse id="My_Ellipse"/>
        </svg>
    </body>
</html>
