Hi Scott
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'
{
class Keyed
{
attribute r : ecore_0::EDouble[?];
attribute s : String[?];
property keyed : Keyed[*]
{
key r , s ;
}
}
}
which at least makes keys useable.
Would
property keyed : Keyed[*|r,s];
be sensible?
Regards
Ed Willink
