title: How do I create an EAttribute whose data type is not an EMF class?
body: <p>Using EMF, I'd like to define an attribute whose data type (EType) is external to my EMF model. That is, the type I want is a normal hand-coded Java class that is not part of my EMF model. Using <code>AnySimpleType</code> is a last resort. I want more type-safety (and less type casting) than using a generic <code>Object</code> provides.</p>
  
  <p>Eclipse's Properties editor restricts EType to a predefined set of values. I can neither enter my own class name nor find a way to add the class I want to the list of options.</p>
