I propose the following text to replace the statement above:

"This specification does not define a content protection or Digital Rights
Management system. Rather, it defines a common API that may be used to
discover, select and interact with such systems as well as with simpler content
encryption systems. Implementation of Digital Rights Management is not required
for compliance with this specification: only the simple clear key system is
required to be implemented as a common baseline.

The common API supports a simple set of content encryption capabilities,
leaving application functions such as authentication and authorization to page
authors. This is achieved by requiring content protection system-specific
messaging to be mediated by the page, rather than assuming out-of-band
communication between the Content Decryption Module and a license or other
server."
