System-wide Property Policy Plug-in</title><shortdesc>System-wide Properties (SwP) are attributes of a device that have

system-wide significance (for example, the power status or device lock status).

The value of any System-wide property is normally independent of the System

State, but the state and different properties can be combined with policy

to generate a new status indications and actions. </shortdesc><prolog><metadata><keywords/></metadata></prolog><taskbody>
