Only classes in the subpackage designated by the <source/> in your
gwt.xml (defaulting to "client" if not specified) are "seen" by the
compiler.
This means you'd have to put a gwt.xml at some package level
containing the interface and inherit it from your GwtResults.gwt.xml.
e.g. in dk/ange/orion/gwt, create Models.gwt.xml file with <source
path="models" />, and in your GwtResult.gwt.xml add an <inherits
name="dk.ange.orion.gwt.Models" />
