[baseten-users] CopyWithZone

[Michael Ruepp]

Hi Tuuka,

how would I then copy an object and its related objects on a best way?

And, how can I work with XML Data types? - I would have returned XML Data as NSXMLDocument instead of NSData. And how can I insert XML? There is no XML Data Type in the Cora Data xcdatamodel.

Thanks, Mike
