This might well be correct. It's expect this style if the resource was
created by a factory which set the following option:
result.getDefaultSaveOptions().put(XMLResource.OPTION_USE_EN CODED_ATTRIBUTE_STYLE,
Boolean.TRUE);

Generally a proxy will have no attributes set and will need to be
resolved first (as in EcoreUtil.resolve) and replaced by the resolved
result.

Trying having a look at what's happening in this block of code in
XMLSaveImpl.saveFeatures(EObject)
case OBJECT_HREF_SINGLE:
{
if (useEncodedAttributeStyle)
{
saveEObjectSingle(o, f);
continue LOOP;
}
else
{
switch (sameDocSingle(o, f))
{
case SAME_DOC:
{
saveIDRefSingle(o, f);
continue LOOP;
}
case CROSS_DOC:
{
break;
}
default:
{
continue LOOP;
}
}
}
break;
}

Initially I had faced a danglinghref exception, which got solved when
the EObjects were set with the proxy URIs.

Now the problem is not dangling exceptions, but as mentioned below.

The work is to serialize (to xml files) data available from the
database. The data were loaded from xml files only (using ecore). Now
to complete the entire flow we need to getback the original data back
from database.

<br>
Existing functionality -

<br>
The XML file loaded to the database using Ecore.
