|
description: A unique key which defines the overwriting semantics for this piece
|
|
|
|
of room state. This value is often a zero-length string. The presence of this
|

State keys starting with an ``@`` are reserved for referencing user IDs, such
|
|
|
|
as room members. With the exception of a few events, state events set with a
|
|
|
|
given user's ID as the state key MUST only be set by that user.
