Empty namespace URI in ecore? [message #669234]

Hi,
I have an XML of the following structure:

<?xml version="1.0" encoding="utf-8" ?>
<langtree>
	<node id="1"/>
	<node id="2"/>
	...
</langtree>

So there's no xmlns attribute at the root element.
But if I want to model this in my ecore and try to remove the namespace URI, I always get an error "The namespace URI '' is not well formed" respectively "The namespace URI 'null' is not well formed".

Is it possible to model it so that the above XML can be parsed and my EMF model gets populated?

Regards Jens

Yes. Try writing a schema for that XML and import that schema to
Ecore. If you invoke Generate Test Code you'll have an XyzExample which
shows you wants needed to read and write unqualified conforming instances...
