Module authn_attribute 

The procedure attribute @authn(maxAge: 300, amr: ["hwk"], acr: ["aal2"]) (ADR 0022, cratestack#1244): how recently and how strongly the caller must have authenticated.

One reader for every consumer: cratestack-parser refuses an @authn it does not read, and cratestack-macros turns what it reads into the operation’s AuthnRequirement. Keys are maxAge (seconds, 1 to one year), amr (methods that must all be present) and acr (acceptable classes, one must match); each at most once, at least one.
