-- | SCIM defines its own content type (application/scim+json). It's
-- intended to be used for all requests and responses; see the first
-- paragraph in the SCIM specification at
-- <https://tools.ietf.org/html/rfc7644#section-3.1>.
--
-- This module contains helpers for handling it. Basically, just write
-- 'SCIM' instead of 'JSON' in all Servant routes.
