IANA Registry for RTCWeb Constrainable Properties
draft-burnett-rtcweb-constraints-registry-05
Abstract
Specifications in W3C's Media Capture Task Force and WebRTC Working
Group have need of a registry in which to maintain a list of
constrainable properties for HTML media and other constrainable
objects. This document defines this registry.

1. Introduction
There is currently one W3C specification (Media Capture and Streams
[W3C.WD-mediacapture-streams-20130903]) that has need of a registry
in which to represent constrainable properties, and it is expected
that others will as well. The specification makes use of a data
structure representing a list of constraints on the HTML media or
media connection to be established. Additionally, the specification
defines methods that are used to query the web browser about its
capabilities. The returned data structure specifies the browser's
capabilities in terms of constraints that it can satisfy. The data
structures and their use are defined as the Constrainable interface
in the aforementioned specification. This document specifies the
registry used to define individual constrainable property names,
their allowed values, and their meanings.
2. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
3. IANA Considerations
This document defines a registry "RTCWeb Constrainable Properties"
for use by W3C specifications needing to indicate constrainable
properties on HTML Media and other constrainable objects, both as
used by web application authors to indicate preferences and as used
by web browsers to indicate constrainable properties they can
satisfy.
