You won't generally get that by default... Also, a schema location
specifies the namespace and the physical location.

The schema location is serialized only if ePackage.getNsURI() is
different from ePackage.eResource().getURI()

Not really. Just a tiny detail. A good technique for controlling the
value of the xsi:schemaLocation is to add someting like this to the
XyzPackageImpl:
@Override
protected Resource createResource(String uri)
{
return super.createResource("http://www.w3schools.com note.xsd"");
}
Hey, I answered this in the FAQ!
