Hi, Timothy,
The XML Resource implementation provided by EMF optionally assigns UUIDs
to its contained EObjects. These are obtained from the
EcoreUtil::generateUUID() method.

Hey Chris,
i've found this useUUIDs() method in XMLResourceImpl, but didn't found a
posiibility to turn this save option on. I thought, that this would be also
an XMLResource save option, but it isn't so. So, cna you tell me, how to
turn this uuid generation on. I would appreciate this.
Thx
Timothy

Hi, Timothy,
It isn't a save option. Your resource implementation needs to override
XMLResourceImpl::useUUIDs() to return true.
At least, this is how GMF's resource implementation does it.
