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.

The Web Application Security Working Group has published a Candidate Recommendation of Secure Contexts. This specification defines “secure contexts”, thereby allowing user agent implementers and specification authors to enable certain features only when certain minimum standards of authentication and confidentiality are met.

The Web Platform Working Group has published a Proposed Recommendation of HTML 5.1.

This specification defines the 5th major version, first minor revision of the core language of the World Wide Web: the Hypertext Markup Language (HTML). 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. Comments are welcome through 13 October 2016.

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.

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.

The TV Control Working Group has published a Working Draft of TV Control API Specification. This specification defines an API for sourcing audio and video media, such as TV and radio from broadcast, IPTV, or other sources, with associated channel and program metadata, and allows presentation of the media using the video and audio HTML elements. The API is agnostic of any underlying audio or video sourcing technologies.
