Version 2.0 of XrML was a radical departure from all that preceded it. Where DPRL and XrML 1.0 contained specific language for machine-actionable rights ("copy" "transfer" "backup" "install" etc.) version 2.0 was an abstract rights language with only a few core elements. The core elements of XrML 2.0 are the ones needed to establish trust between systems so that transactions can take place. These include the issuer of the license, the other parties to the license, and the ability to include resources and rights, digital signatures, etc. This version is not specific to any medium or type of resource, and has been generalized to control rights on digital resources, services, or any other digital entity.
