XSD2JavaGenerator doesn't generate DocumentRoot class
Greetings,
I am attempting to migrate my application from EMF/SDO 1.0 to Tuscany SDO 2.0. I noticed that the Tuscany code generator is not generating a DocumentRoot class for my schema. My application serializes/de-serializes DataGraphs across tiers. Currently, when building a DataGraph, we create a DocumentRoot, set is as the root dataobject on the datagraph, set a global element instance on the DocumentRoot, and then pass the DataGraph over the wire. Is the "dummy" DocumentRoot no longer used/needed/recommended?
Thanks in advance for your assistance.

Frank,
I opened JIRA "TUSCANY-512" to track this feature.
Thanks,

Ron,
It looks like in SDO 2.1 there will probably be a standard way to set the
root object. Right now, however, there is no "spec recommended" way. If
you'd like, we can add another SDOUtil method -
SDOUtil.setRootObject(DataGraph dataGraph, DataObject rootObject) - so you
don't need to call the implementation-specific (setERootObject) method,
which will be removed in the future. Please open a JIRA if you'd like us
to do that.
Thanks,
Frank.

Re: XSD2JavaGenerator doesn't generate DocumentRoot class
Makes sense. Indeed, the "dummy" DocumentRoot object was quite
inconvenient to work with.
I often use XMLHelper to load a DataObject that I want to serve as the
root object in my data graph. Without a "setRootObject()" method, what is
the "recommended" way to attach this XMLHelper-loaded DataObject as the
root object of a DataGraph? I used to use the EMF APIs to accomplish this
type of task.

The DocumentRoot is not needed. DocumentRoot is an EMF concept, so in SDO
2 we don't expose it to clients. You also can't set the root object in a
DataGraph using standard SDO APIs. You can currently only set it by
calling DataGraph.createRootObject(). SDO 2.1 is going to clarify the
DataGraph API further, so you might want to keep your eye on the next
round of spec changes.
