The CSS Working Group invites implementation of two Candidate Recommendations:

• CSS Grid Layout Module Level 1: This CSS module defines a two-dimensional grid-based layout system, optimized for user interface design. In the grid layout model, the children of a grid container can be positioned into arbitrary slots in a predefined flexible or fixed-size layout grid.
• CSS Values and Units Module Level 3: This CSS module describes the common values and units that CSS properties accept and the syntax used for describing them in CSS property definitions.

This is a public call for prior art regarding patent disclosures by Visa Europe within the Web Payments Working Group.

The goal of this call for prior art is to collect information that would help to ensure that people may implement the (future) Recommendations of the Web Payments Working Group under patent licensing terms consistent with the Royalty-Free Licensing Requirements of the W3C Patent Policy. Specifically, W3C seeks prior art available under terms consistent with W3C’s RF licensing terms or in the public domain.

While W3C welcomes information at any time, responses as soon as possible and ideally before 31 December 2016 are encouraged. See the call for prior art for instructions on how to send responses.

On 19 July 2016, pursuant to its rights under W3C’s Patent Policy, Visa Europe disclosed a number of patents and patent applications and excluded claims from Royalty-Free licensing for two specifications from the Web Payments Working Group: Payment Request API and Payment Method Identifiers. In accordance with the exception procedures of the Patent Policy, W3C launched the Web Payments Working Group Patent Advisory Group (PAG) to determine possible solutions. The PAG has advised W3C to issue this call for prior art.

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.

• Working on HTML5.1
• Finishing HTML5.1 … and starting HTML 5.2

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 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.
