title: What is the single best free Eclipse plugin for authoring and editing XML documents?
body: <p>In my old job I used XMLSpy to do my XML authoring and editing, but now I require a free plugin for Eclipse to do this. My basic requirements are:</p>
  
  <pre><code>- General XML document editing
  - Creating XSD files
  - Creating WSDL files
  </code></pre>
  
  <p>Can you recommend a free Eclipse plugin for this?</p>
