//! `inbuxa:AccountLock/get` and `/set` under `urn:inbuxa:jmap`: an account
//! locked, and the people it is handed to (audit-hold-lock spec, AL-1 to
//! AL-12). A lock's id is the locked account's id. Creating one locks the
//! account, updating changes its delegates, destroying unlocks it. The set
//! call's `reason` argument says why, for the audit log (AU-12); creating
//! takes it as a property.
