-------------------------------------------------+-------------------------
 We agreed (on IRC) to change the {{{?mutable-type=}}} query parameter to a
 {{{?format=}}} parameter with options {{{chk}}}, {{{sdmf}}}, and
 {{{mdmf}}}. For compatibility, the {{{?mutable=true}}} flag would still be
 accepted and would mean the same as {{{?format=sdmf}}} (at least for now).
 The values should be case-insensitive.

 This way, if we add a new immutable format in future, it won't require a
 new query parameter. This also makes the implementation of #1547 easier.
