title: cvc-elt.1.a: Cannot find the declaration of element '…'
body: <p>My XSD is as follows: </p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8" standalone="yes"?&gt;
  &lt;xs:schema version="1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema"&gt;
  &lt;xs:complexType name="AppRegisterConfig"&gt;
      &lt;xs:sequence&gt;
          &lt;xs:element name="restServiceUrl" type="xs:string" /&gt;
          &lt;xs:element name="timeout" type="xs:int" /&gt;
          &lt;xs:element name="attempts" type="xs:int" /&gt;
      &lt;/xs:sequence&gt;
  &lt;/xs:complexType&gt;
  </code></pre>
  
  <p>  </p>
  
  <p>My XML is as below:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;appregister-config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:noNamespaceSchemaLocation="appregister-config.xsd"&gt;
  
    &lt;restServiceUrl&gt;&lt;url&gt;url 1&lt;/url&gt;&lt;/restServiceUrl&gt;
    &lt;timeout&gt;15000&lt;/timeout&gt;
    &lt;attempts&gt;5&lt;/attempts&gt;  
  &lt;/appregister-config&gt;  
  </code></pre>
  
  <p>Any idea what I may have missed?</p>
