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.
*** This is correct. But the "text ID" (GUID) is used only as a last resort. That
basically boils down to derived pointers. In other cases, the archive local
class id can be generated and used instead. So that's what the serialization
library does
