title: Mule: How can project configs cause such misleading SAX errors?
body: <p>I've fixed the problem below, but since I've hit this more than once and wasted time on it, I'd like to better understand the chain of events that cause the misleading error.</p>
  
  <p>Scenario:</p>
  
  <ul>
  <li>Mule throws a giant SAX exception parsing your XML, indicating unexpected content</li>
  <li>But the XML is fine, it works OK in another project</li>
  <li>If you add dependencies etc, eventually this project will accept the XML as well</li>
  </ul>
  
  <p>The *flavor" of the error is:  (full stack below)</p>
  
  <pre><code>org.xml.sax.SAXParseException: cvc-complex-type.2.4.a:
  Invalid content was found starting with element 'zendesk:config'. One of ... is expected.
  </code></pre>
  
  <p>Where <code>zendesk:config</code> can vary, and where it's prefix and xsd are correctly defined in the XML header.</p>
  
  <p>In comparing projects that do and don't work with the same XML, I see these differences:</p>
  
  <ul>
  <li>mulesoft-project.xml has an additional muleExtension</li>
  <li>pom.xml has extra inclusions and dependencies</li>
  <li>.classpath has some extra classpath entries, kind="var" path="M2_REPO/..."</li>
  <li>target/mvn-eclipse-cache.properties has some extra entries</li>
  </ul>
  
  <p><strong>But how do these differences give such a horribly unhelpful stack trace?</strong></p>
  
  <p>Mostly Full error: (redacted for stackoverflow post limits)</p>
