title: Free XML Editor for custom XSD
body: <p>Our component is configurable using an XML API and we have an XSD that defines this XML-API. </p>
  
  <p>Now, what is the best way our customers could get context sensitive help while creating our XML API? Is there a free tool they could download (or we could distribute) that will take in an XSD and provide context senstive help for the edited XML?</p>
  
  <p>Thanks</p>
