 Initial Assignment for the Content Security Policy Directives Registry

Abstract

   This document establishes an Internet Assigned Number Authority
   (IANA) registry for Content Security Policy directives and populates
   that registry with the directives defined in the Content Security
   Policy Level 2 specification.

1.  Introduction

   The Content Security Policy (CSP) specification [CSP] defines a
   mechanism that web developers can use to control the resources that a
   particular page can fetch or execute, as well as a number of
   additional security-relevant policy decisions.

   The policy language specified in that document consists of an
   extensible set of "directives", each of which controls a specific
   resource type or policy decision.  This specification establishes a
   registry to ensure that extensions to CSP are listed and
   standardized.

2.  Terminology

   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 [RFC2119].

3.  Use of the Registry

   Content Security Policy directives must be documented in a readily
   available public specification in order to be registered by IANA.
   This documentation MUST fully explain the syntax, intended usage, and
   semantics of the directive.  The intent of this requirement is to
   assure interoperable independent implementations, and to prevent
   accidental namespace collisions between implementations of dissimilar
   features.

   Documents defining new Content Security Policy directives MUST
   register them with IANA, as described in Section 3.  The IANA
