This article currently has a pro-DRM bias. - Sikon 08:38, 14 June 2006 (UTC)

The MPEG-21 spec has many parts. 3 parts of this are related to licensing and similar concerns (Part 4: IPMP, Part 5: REL, Part 6: RDD). Yet anyone reading this article would presume that these things were practically the only feature of MPEG-21. Propagation of license information is certainly *a* part of MPEG-21, but it is far from the *only* part. Indeed, MPEG-21 at this point in time does not provide a DRM system at all; the IPMP defines mechanisms to allow different (proprietary) DRM systems to interoperate, but does not contain the encryption or other security systems required to actually create and enforce a DRM system.
