The patch on https://bugs.eclipse.org/bugs/show_bug.cgi?id=324924 will
serialize a simple test file to
import ecore_0 : 'http://www.eclipse.org/emf/2002/Ecore#/';
package keys : ky = 'http://keys'
attribute r : ecore_0::EDouble[?];
attribute s : String[?];
property keyed : Keyed[*]
key r , s ;
which at least makes keys useable.
property keyed : Keyed[*|r,s];
