This documentation refers to individual protocol features, it links to the implementation and technical documentation for each subsystem.
Each subsystem should be using its own prefix for capabilities and packet types. (most already do)
Most modules are optional, see security considerations.
Most subsystems are independent of each other, except for:
Display
subsystem is required by
Windows

subsystem is required by the
Keyboard
, Pointer
and Cursors
subsystemsA client or server may choose to completely disable a
subsystem.
When this is the case, it will not load the module into memory and will
not know how to handle requests for this feature.
