Your other points notwithstanding, a minor correction to your examples, since it is possible and quite common to embed metadata in video and audio:


http://www.adobe.com/devnet/xmp/

"Part 3, Storage in Files (PDF, 629k) , provides information about how serialized XMP metadata is packaged into XMP Packets and embedded in different file formats. It includes information about how XMP relates to and incorporates other metadata formats, and how to reconcile values that are represented in multiple metadata formats."

Note also availability of free open source implementation:

The XMP Toolkit allows you to integrate XMP functionality into your product or solution. It supports Macintosh, Windows, as well as UNIX and comes with samples, documentation, source code and project files. The XMP Toolkit is available under the BSD license. The specification is provided under the XMP Specification Public Patent License (PDF, 24k).
