XmrLicense

A parsed XMR license — the binary payload a PlayReady server returns inside its SOAP response.

The source bytes are kept: the licence's integrity CMAC covers everything before its signature object, and re-encoding a tree whose policy objects we deliberately do not model would not reproduce those bytes.
