Media Feature Tag Registration Procedure

Recent Internet applications, such as the World Wide Web, tie together
a great diversity in data formats, client and server platforms, and
communities. This has created a need for content feature descriptions
and negotiation mechanisms in order to identify and reconcile the form
of information to the capabilities and preferences of the parties
involved. Extensible content feature identification and negotiation
mechanisms require a common vocabulary in order to positively identify
content features. A registration process and authority for content
features is defined with the intent of sharing this vocabulary between
communicating parties. In addition, a URI tree is defined to enable
sharing of content feature definitions without registration. This
document defines a registration procedure which uses the Internet
Assigned Numbers Authority (IANA) as a central registry for the
content feature vocabulary.
