title: JAXB Compiling Issue - [ERROR] Property "Any" is already defined
body: <p>I am trying to create JAXB binding for xccdf-1.1.4.xsd which is a standard schema that can be obtain from <a href="http://scap.nist.gov/specifications/xccdf/#resource-1.1.4" rel="noreferrer">XCCDF Schema Location</a></p>
  
  <p>I am currently using EclipseLink MOXy as my JAXB implementation since I like the fact that it can also generate JSON bindings as well.</p>
  
  <p>I fixed couple of occasion where I hit the infamous "[ERROR] Property "value" is already defined" error using an external binding XML, and now I am hitting an error on</p>
  
  <pre><code>[ERROR] Property "Any" is already defined. Use &amp;lt;jaxb:property&gt; to resolve this conflict.
  line 441 of file:/home/dchu/Playground/Java/eclipselink_moxy/xccdf_1.1.4/xccdf-1.1.4.xsd
  
  [ERROR] The following location is relevant to the above error
  line 444 of file:/home/dchu/Playground/Java/eclipselink_moxy/xccdf_1.1.4/xccdf-1.1.4.xs
  </code></pre>
  
  <p>Below is a snippet of the line in the XML schema where the error occurred.</p>
  
  <pre><code>&lt;xsd:sequence&gt;
      &lt;xsd:choice minOccurs="1" maxOccurs="1"&gt;
        &lt;xsd:any namespace="http://purl.org/dc/elements/1.1/"
                 minOccurs="1" maxOccurs="unbounded"/&gt;
        &lt;xsd:any namespace="http://checklists.nist.gov/sccf/0.1"
                 processContents="skip" 
                 minOccurs="1" maxOccurs="unbounded"/&gt;
      &lt;/xsd:choice&gt;
  &lt;/xsd:sequence&gt;
  </code></pre>
  
  <p>Does anyone knows what could be wrong here?  Thanks!</p>
