Upstream says definitely not. The UUIDs are supposed to be unique and they
don't want anyone writing fixed UUIDs into documents (except for "" for the
instance ID which they themselves do).
I think there could be some enterprise search engine which associates a
document with other resources using the document UUID - and if everyone went
and reused UUIDs it would be very confused.
That's why I left it off.
