Sven,
No, there's nothing in EMF that keeps a temporal order. The order in
features is the order in which they are inserted in the list. The
overall eContents() order across features is controlled by the order of
the features in the EClass and then within features, the order in which
they appear in their list. If you define a type with mixed content,
then all the features would defer to the mixed content feature and in
that case you'd get things in a mixed order (which might not actually
conform to the schema).
