title: element web-app must be declared
body: <p>I checked out this project from svn repository into IDEA and the web.xml xsd looks like this:</p>
  
  <pre><code>&lt;web-app id="data-fabric-web-tool" version="2.5"
       xmlns="http://java.sun.com/xml/ns/j2ee"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
       http://java.sun.com/xml/ns/j2ee/web-app_2_5.xsd"&gt;
  </code></pre>
  
  <p>The very first error I see is "Element web-app" must be declared.
  Also I am getting "cannot resolve symbol" error for every tag in the file.</p>
