Clarification for Verification Method expires/revoked

[lemoustachiste]

Hi,

so it's a subtle doubt I have regarding the expires and revoked verification method properties.

As a verifier should we treat any verification after one of those dates as invalid, or only proofs issued after these dates as invalid, meaning that any signature that occurred before expiration or revocation are still valid?

The wording is not clear to me although I tend to lean towards the first option:

not verify any proofs associated with the verification method at or after the time of expiration.

Thanks for the clarification.
