Version Control / Cred-Ledger

Where a credential is updated as a counterpart to a series that may benefit
from provenance inspection and/or ledger like functionality, what are the
considerations?

The theory is that each-time the document is updated, perhaps a reference
to 'latest' and/or historical may be a better approach vs. invalidating the
out of date document without means to look-up and related documents...?

the other aspect within there is also invalidation of document.  Whether
that means it's simply valid or not, or whether it can still be valid for a
period of time.

I think law is a use-case for examining that concept; where acts are passed
updating the law, however law as it relates to a historical act may relate
to the former version.
