title: Not well-formed: the end-tag for element type xs:element must end with a '>' delimiter
body: <p>I have created XML files and associated XSD Schemas but the online verifier said it still remains errors in my XSD Schemas.</p>
  
  <p>The exact error it shows is: </p>
  
  <pre><code>Not well-formed: the end-tag for element type 
  xs:element" must end with a '&gt;' delimiter.
  </code></pre>
  
  <p>Here is the XSD:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;xs:schema xmlns:xs="http://www.w3schools.org/2001/XMLSchema/"&gt;
  
  &lt;xs:element name="List_Of_Skills" maxOccurs="unbounded"&gt;
  &lt;xs:complexType&gt;
  &lt;xs:sequence&gt;
  
      &lt;xs:element name="Skill" maxOccurs="unbounded"&gt;
      &lt;xs:complexType&gt;
      &lt;xs:sequence&gt;
  
      &lt;xs:element name="ID" type="xs:integer"/&gt;
      &lt;xs:element name="Name" type="xs:string"/&gt;
      &lt;xs:element name="Description" type="xs:string"/&gt;
  
      &lt;/xs:sequence&gt;
      &lt;/xs:complexType&gt;
      &lt;/xs:element name="Skill"&gt;
  
   &lt;/xs:sequence&gt;
  &lt;/xs:complexType&gt;
  &lt;/xs:element name="List_Of_Skills"&gt;
  
  &lt;/xs:schema xmlns:xs="http://www.w3schools.org/2001/XMLSchema/"&gt;
  </code></pre>
  
  <p>By the way my XML code is well formed so I don't understand why my XSD code isn't valid even if I thought I understood how it works.</p>
