In this version, new features continue to be introduced to help Web application authors, new elements continue to be introduced based on research into prevailing authoring practices, and special attention continues to be given to defining clear conformance criteria for user agents in an effort to improve interoperability.

First Public Working Drafts of Web Payments HTTP Specifications

15 September 2016 | Archive

The Web Payments Working Group has published First Public Working Drafts of the following specifications, which enable the initiation of payment requests outside of a browser context:

  • Web Payments HTTP API 1.0 outlines how to register payment applications, create payment requests, and reply with payment responses using a standard HTTP API.
  • Web Payments HTTP Messages 1.0 specifies the Web Payments messages that are used to initiate and acknowledge a payment request via the HTTP protocol. The messages are typically passed between the software ecosystem that inititates, executes, and finalizes Web Payments.

The Working Group welcomes feedback on these early drafts.

Secure Contexts published as a Candidate Recommendation

W3C Invites Implementations of Scalable Vector Graphics (SVG) 2

15 September 2016 | Archive

The SVG Working Group has published a Candidate Recommendation of Scalable Vector Graphics (SVG) 2. This specification defines the features and syntax for Scalable Vector Graphics (SVG) Version 2. SVG is a language based on XML for describing two-dimensional vector and mixed vector/raster graphics. SVG content is stylable, scalable to different display resolutions, and can be viewed stand-alone, mixed with HTML content, or embedded using XML namespaces within other XML languages. SVG also supports dynamic changes; script can be used to create interactive documents, and animations can be performed using declarative animation features or by using script.

Call for Review: WebIDL Level 1 Proposed Recommendation Published

15 September 2016 | Archive

The Web Platform Working Group has published a Proposed Recommendation of WebIDL Level 1. This document defines an interface definition language, Web IDL, that can be used to describe interfaces that are intended to be implemented in web browsers. Web IDL is an IDL variant with a number of features that allow the behavior of common script objects in the web platform to be specified more readily. How interfaces described with Web IDL correspond to constructs within ECMAScript execution environments is also detailed in this document. It is expected that newly published specifications reference this document to ensure conforming implementations of interfaces are interoperable. Comments are welcome through 14 October.

13 September 2016 | Archive

The Web Application Security Working Group has published 3 Notes:

  • Content Security Policy: Cookie Controls: This Note provides a historical reference for a proposed set of mechanisms by which web developers can limit the ways in which cookies may be set in the context of their sites and applications.
  • Content Security Policy: Pinning: This Note provides a historical reference for a proposed mechanism to allow authors to instruct user agents to remember (“pin”) and enforce a Content Security Policy for a set of hosts for a period of time.
  • Entry Point Regulation: This Note provides a historical reference for a proposed mechansim to mitigate the risk of reflected cross-site scripting (XSS), cross-site script inclusion (XSSI), and cross-site request forgery (CSRF) attacks by demarcating the areas of an application which are intended to be externally referencable. A specified policy is applied on external requests for all non-demarcated resources.
