One would expect trust anchors to remove old entries, but there is no guarantee. Russ asked if IANA could purge expired trust anchors from the registry. It’s not straightforward, although possible.

The current draft says, “IANA SHOULD remove a STIR trust anchor from the registry if the certificate expires."

Options I see:
1. Leave this as a SHOULD and IANA works it out when and if they work it out.
2. Make it a MUST and specify how IANA does the purge.
3. ???



TO DO
=====
1. Put in a mechanism for removing / updating entries. Proposal: whomever (domain) put in the entry can delete or modify the entry.

2. Add language that registry users are URGED (VERY STRONG MAY) to validate the trust anchor, like making sure the trust anchor has not expired.
