I can't seem to find a list of current possible signature Proof Purposes
for listing in DID Documents and using for VCs and zCaps. The best i can
find is from 2018 from David Longley <dlongley@digitalbazaar.com>:

"authentication" => "<vocab>#authenticationMethod"
"assertionMethod" => "<vocab>#assertionMethod"
"capabilityInvocation" => "<vocab>#capabilityInvocationMethod"
"capabilityDelegation" => "<vocab>#capabilityDelegationMethod"
"contractAgreement" => "<vocab>#contractAgreementMethod"

Is this correct? Are there more? Have some of these been deprecated?

In particular, I'm wondering where timestamps fit in, and other kinds of
proofs besides signatures.
