The intent of this specification is to specify a mechanism to allow the
configuration of settings such as double click timeout, drag-and-drop
threshold, and default foreground and background colors for all applications
running within a desktop. The mechanism should:
- allow for instant updates to be propagated across all applications at runtime
- perform well, even for remote applications.

It is not intended:
- for the storage of application-specific data
- to be able to store large amounts of data
- to store complex data types (other than as strings)
