title: Restricting empty elements in xsd
body: <p>Is there a way to prevent empty elements of the form <code>&lt;myElement/&gt;</code> being used in your xml? In other words, can you specify in your xsd that <code>&lt;myElement/&gt;</code> is invalid?</p>
  
  <p>Using <code>nillable="false"</code> doesn't work, nor does <code>minOccurs="1"</code> - both of those allow 
  <code>&lt;myElement/&gt;</code>.</p>
