Hi,

I am a bit confused about the purpose of GUID. My understanding was, that it is a user defined id for a class, so that the serialization mechanism knows what types to instanciate on load. I somehow assumed it to be a replacement (or equivalent) of the numbers in the class_id attributes.

*** You're correct. But the GUID is used only when the more robust method of

an archive local class ID is not possible.
