A ``public`` visibility indicates that the room will be shown
in the published room list. A ``private`` visibility will hide
the room from the published room list. Rooms default to
``private`` visibility if this key is not included. NB: This

word ``public``.

The desired room alias **local part**. If this is included, a

created the room. For example, if this was set to "foo" and
sent to the homeserver "example.com" the complete room alias
would be ``#foo:example.com``.

Convenience parameter for setting various default state events

``public_chat`` and ``private`` visibility equates to a preset of
``private_chat``.

Add general clarity to the /createRoom endpoint This commit does a number of things: * Minor formatting/alignment changes * Document the room_alias response key. This could be deprecated now, or forfeited, if needed. * Remove the guest_can_join parameter - it is not actually supported * Document the previously undocumented power_level_content_override parameter * Clarify that the room_id is required on the response * More clearly spell out which events are created as part of the request * Clarify how the room alias becomes the canonical alias * Clarify how the `visibility` may be used to determine a default preset to apply * Document the `m.federate` creation content parameter, adding an option for the homeserver to define a default value References: * Preset being inferred by the visibility: https://github.com/matrix-org/synapse/blob/cd32c19a604549b4518d748c07149d140bc9e063/synapse/handlers/room.py#L172-L177 * Power level content overrides: * https://github.com/matrix-org/synapse/blob/master/synapse/handlers/room.py#L198 * https://github.com/matrix-org/synapse/blob/master/synapse/handlers/room.py#L335-L359 * Aliases becoming canonical: https://github.com/matrix-org/synapse/blob/master/synapse/handlers/room.py#L366-L370 * `m.federate` landing in the create event: https://github.com/matrix-org/synapse/blob/master/synapse/handlers/room.py#L311-L315 Fixes https://github.com/matrix-org/matrix-doc/issues/1243 Fixes https://github.com/matrix-org/matrix-doc/issues/1471 Inspired by https://github.com/matrix-org/matrix-doc/issues/1213

The request is invalid. A meaningful ``errcode`` and description
error text will be returned. Example reasons for rejection include:
- The request body is malformed (``errcode`` set to ``M_BAD_JSON``
or ``M_NOT_JSON``).
- The room alias specified is already taken (``errcode`` set to
``M_ROOM_IN_USE``).
- The initial state implied by the parameters to the request is
invalid: for example, the user's ``power_level`` is set below
that necessary to set the room name (``errcode`` set to
``M_INVALID_ROOM_STATE``).
- The homeserver doesn't support the requested room version, or
one or more users being invited to the new room are residents
of a homeserver which does not support the requested room version.
The ``errcode`` will be ``M_UNSUPPORTED_ROOM_VERSION`` in these
cases.
