In page XrML:

"

XrML 1.0 was an evolution of DPRL. It expanded much of the management structure of DPRL, adding unique identifiers, private and public keys, and other mechanisms for identifying and verifying the authenticity of the issuer and the user of the resource. It also added certification for hardware and software that would be part of the trusted environment. The rights list remained the same, although the definitions of individual rights changed somewhat. In particular, XrML 1.0 distinguished clearly between those rights that created a new resource versus those that modified an existing resource.
