This resource describes the properties (regulated, has real time clock, etc.), adminstrative (manufacturer name, model number, serial number, firmware, etc.), and type (knee replacement, blood pressure cuff, MRI, etc.) of a physical unit (these values do not change much within a given module, for example the serail number, manufacturer name, and model number). An actual unit may consist of several modules in a distinct hierarchy and these are represented by multiple Device resources and bound through the 'parent' element.
