Introduction There is currently one W3C specification (Media Capture and Streams - [W3C.WD-mediacapture-streams-20130903]) that has need of a registry + [W3C.WD-mediacapture-streams-20150212]) 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 Pattern in the aforementioned specification. This document specifies the registry used to define individual constrainable property names, @@ -125,37 +125,37 @@ 3.1.1. Designated Expert Instructions RTCWeb Constrainable Property Names are of unlimited length according to the syntax. However, it is RECOMMENDED that they be no longer than 80 characters in total. This is to keep them reasonable for humans to read and use. It is RECOMMENDED that Names use camel case, i.e., when a Name consists of multiple words, the first character of each word SHOULD be an uppercase character, with all others being lowercase. - The references MUST define the following for each RTCWeb + The References MUST define the following for each RTCWeb Constrainable Property: allowed values - The references MUST define the allowed values for the property, + The References MUST define the allowed values for the property, for example an enumerated list of values or a range of integers. object(s) - The references MUST define the object or objects for which the + The References MUST define the object or objects for which the properties apply, for example a MediaStreamTrack.

Security Considerations Since the constrainable properties envisioned for this registry are fairly generic in nature, it is not expected that the mere existence of this registry will introduce any particular security issues. Any specification defining one or more new properties SHOULD address any specific security issues that might be introduced by the properties or their constrainable values. @@ -169,26 +169,26 @@ [RFC5234] Crocker, D. and P.
