`
`Auniversal plug and play (UPnP) device makes itselfknown
`through a set of processes-discovery, description, control,
`eventing, and presentation. Following discovery of a UPnP
`device, an entity can learn more about the device and its
`capabilities by retrieving the device's description. The
`description includes vendor-specific manufacturer informa-
`tion like the model name and number, serial number, manu-
`facturer name, URLs to vendor-specific Web sites, etc. The
`description also includes a list of any embedded devices or
`services, as well as URLs for control, eventing, and presen-
`tation. The description is written by a vendor, and is usually
`based on a device template produced by a UPnP forum
`working committee. The template is derived from a template
`language that is used to define elements to describe the
`device and any services supported by the device. The
`template language is written using an XML-based syntax
`that organizes and structures the elements.
