1 . A DRM system comprising: 
 a service provider;    a CE device coupled to the service provider; and    an XMR license disposed upon the CE device.    
   
   
       2 . The DRM system of  claim 1 , in which the XMR license is sent from a service provider to the DRM device via an internet connection.  
   
   
       3 . The DRM system of  claim 1 , in which the XMR license is binary.  
   
   
       4 . The DRM system of  claim 1 , in which the XMR license is extensible.  
   
   
       5 . The DRM system of  claim 1 , in which the XMR license includes a must understand field.  
   
   
       6 . The DRM system of  claim 5 , in which the XMR license includes a plurality of objects with each object of the plurality of objects includes the must understand field.  
   
   
       7 . The DRM system of  claim 6 , in which the must understand field present in each object of the plurality of objects is configured to cause an XMR parser to ignore an object of the plurality of objects that the XMR parser does not understand.  
   
   
       8 . The DRM system of  claim 1 , in which the XMR license includes a content key object formed by combining a content key and an integrity key.  
   
   
       9 . An XMR license comprising: 
 an XMR header object; and    an XMR container object.    
   
   
       10 . The XMR license of  claim 9 , in which the XMR container object comprises a plurality of child objects each having a header including a must understand field.  
   
   
       11 . The XMR license of  claim 9 , in which the XMR container object is extensible to allow the addition of additional objects to the XMR license.  
   
   
       12 . The XMR license of  claim 9 , in which the XMR container object includes a nested structure for the addition of additional objects.  
   
   
       13 . An XMR license comprising: 
 an XMR header object; and    an XMR container object including a global policy container and a plurality of additional container objects.    
   
   
       14 . The XMR license of  claim 13 , additionally comprising an XMR signature object.  
   
   
       15 . The XMR license of  claim 13  in which the XMR key material container object includes a content key object.  
   
   
       16 . The XMR license of  claim 13  in which one of the plurality of container objects comprises a plurality of child objects.  
   
   
       17 . The XMR license of  claim 13  in which the XMR container object provides extensibility.  
   
   
       18 . The XMR license of  claim 13  in which the XMR license is binary.  
   
   
       19 . The XMR license of  claim 13  in which one of the plurality of container objects comprises a must understand field.  
   
   
       20 . The XMR license of  claim 13  in which the global policy container includes a minimum environment restriction object.
