+// PoliciesDefaultsPATCHHandler swagger:operation PATCH /api/v1/interaction_policies/defaults policiesDefaultsUpdate
+//
+// Update default interaction policies per visibility level for new statuses created by you.
+//
+// If submitting using form data, use the following pattern:
+//
+// `VISIBILITY[INTERACTION_TYPE][CONDITION][INDEX]=Value`
+//
+// For example: `public[can_reply][always][0]=author`
+//
+// Using `curl` this might look something like:
+//
+// `curl -F 'public[can_reply][always][0]=author' -F 'public[can_reply][always][1]=followers'`
+//
+// The JSON equivalent would be:
+//
+// `curl -H 'Content-Type: application/json' -d '{"public":{"can_reply":{"always":["author","followers"]}}}'`
+//
+// Any visibility level left unspecified in the request body will be returned to the default.
+//
+// Ie., in the example above, "public" would be updated, but "unlisted", "private", and "direct" would be reset to defaults.
+//
+// The server will perform some normalization on submitted policies so that you can't submit totally invalid policies.
