Review Request: The Codecs Parameter for "Bucket" Media Types

[Randall Gellens]

draft-gellens-mime-bucket-00 proposes adding a new parameter to 
certain media types:

Abstract

     Several MIME type/subtype combinations exist which can contain
     different media formats.  A receiving agent thus needs to examine
     the details of such media content to determine if the specific
     elements can be rendered given an available set of codecs.
     Especially when the end system has limited resources, or the
     connection to the end system has limited bandwidth, it would be
     helpful to know from the Content-Type alone if the content can be
     rendered.

     This document adds a new parameter, "codecs", to various
     type/subtype combinations to allow for unambiguous specification of
     the codecs required to support the media formats contained within.

     By labelling content with the specific codecs required to render the
     contained media, receiving systems can determine if the codecs are
     supported by the end system, and if not, can take appropriate action
     (such as rejecting the content, sending notification of the
     situation, transcoding the content to a supported type, fetching and
     installing the required codecs, etc.)
