Ugur,
You need to enter true or false in the Properties view for the Default
Value Literal feature for the EAttribute of your model. It should be there.

EMF can serialize any instance to XML.

How so and by whom?

What's the dilemma?

You just need to put all your objects in one or more resources and they
should just serialize. What aspect of that isn't working well for you?

You can specialize a resource's getURIFragmentRootSegment and
getEObjectForURIFragmentRootSegment methods.

Yes, features for which eIsSet if false don't need to be serialized.

Try OPTION_KEEP_DEFAULT_CONTENT.

Ugar,
Did you also set an explicit default on the feature itself? Except for
primitive types, all features implicitly default to null. For
primitives, they default to the same value as the implicit Java
default. You'll need to set an explicit default if you want something
serialized with that option.

Ugar,
You do that in the properties view in the editor by specifying either
the string false or true for the Default Value Literal.
