OpenSimulator talk:Xml Serialization

Diva's comments
I would like the new format to reflect two different intentions of external representations: (1) object serialization; (2) templates for object creation. Right now, only (1) is addressed. For addressing (2), all we need to do is to give new identifiers to the different parts of the objects. So during deserialization, identifiers should be assumed to be optional.
