The non standardization of video/audio codecs has historically been
contested leading to today where no single codec can be used across
implementations. The <object> specification is content agnostic and does
not concern itself with specifica of the implementations of either
silverlight or flash, while the HTML-DRM specification does. Regardless a
retirement of the <object> in favor of standardized approaches is lauded
from all sides, even from the providers of such content.

Websockets, HTTP, TLS etc. are specified by the IETF, is it in the charter
of the IETF to specify the HTML-DRM protocol?

Because it is the first use-case, and hurdle, to overcome to measure the
success of the specification. A success criteria which I consider failed
thus far.

So you agree that HTML-DRM is not implementable in a fashion compatible
with the HTML-WG charter, while retaining its usefulness to the usecase it
should satisfy.
