rights.xml is an Adobe-specific thing, used by ACS/ADE, and it's in the standard because it's left over from the original definition of EPUB (well, OEBPS back then) that came out of Adobe. Its contents aren't standardized by anyone except Adobe, internally.

The draft spec covers a few things, and a quick overview can be found on the W3C site[2]. The basics are:

• Encryption via XML-ENC 1.1/2.0 for content protection/locking.
• Digital Signatures via XML-DSig 1.1/2.0 for content verification and potentially device/user verification.
• An XML schema describing chained authentication methods (use built in account info, if that fails prompt for email/password, etc.)
• An XML schema specifying individual rights in a granular and openly extensible manner, including support for both personal and institutional lending.

Howzat!
