Yes of course I meant to say ...GCT...

I had obviously read that message before. Unfortunately we do not even
seem to agree on the basic concepts. For me a document has many ODF xml
representations and changing between those representations does not
represent a document change, so while GCT may be well suited to for
recording changes in the representation I fail to see how it can be used
successfully to recognize changes to the document itself.

I think there is fundamentally a difference between recording document
changes and recording changes in xml-representation.
