The mission of this group is to define an API that lets developers implement secure application protocols on the level of Web applications, including message confidentiality and authentication services, by exposing trusted cryptographic primitives from the browser. Web application developers will no longer have to create their own or use untrusted third-party libraries for cryptographic primitives. This will improve security on the Web.
The mission of the Web Notification Working Group, part of the Rich Web Client Activity, is to produce specifications that define APIs to generate notifications to alert users. A Notification in this context may be displayed asynchronously and may not require user confirmation. Additionally, events are specified for managing user interactions with notifications.

These APIs should enable building applications that can be run inside a browser, requiring no extra downloads or plugins, that allow communication between parties using audio, video and supplementary real-time communication, without having to use intervening servers.
The mission of the Web Fonts Working Group is to develop specifications that allow the interoperable deployment of downloadable fonts on the Web. Existing specifications (CSS3 Fonts, SVG) explain how to describe and link to fonts, so the main focus will be the standardisation of font formats suited to the task, and a specification defining conformance (for fonts, authoring tools, viewers, etc.) all the technology required for WebFonts.
The XML Processing Model Working Group is defining XProc, an XML-based language that allows the creator of any given XML document to indicate that operations on that document should be performed in a specific order for a particular result, and if so, how to apply those operations.
The mission of the XML Query Working Group is to provide flexible query facilities to extract data from XML and virtual documents, such as contents of databases or other persistent storage that are viewed as XML via a mapping mechanism, on the Web.
The mission of the XSL Working Group is to define and maintain a practical style and transformation language capable of supporting the transformation and presentation of, and interaction with, structured information (e.g., XML documents) for use on servers and clients. The language is designed to build transformations in support of browsing, printing, interactive editing, and transcoding of one XML vocabulary into another XML vocabulary. To enhance accessibility, XSL is able to present information both visually and non-visually. XSL is not intended to replace CSS, but will provide functionality beyond that defined by CSS, for example, element re-ordering.
The mission of the Digital Publishing Interest Group is to provide a forum for experts in the digital publishing ecosystem of electronic journals, magazines, news, or book publishing (authors, creators, publishers, news organizations, booksellers, accessibility and internationalization specialists, etc.) for technical discussions, gathering use cases and requirements to align the existing formats and technologies (e.g., for electronic books) with those used by the Open Web Platform. The goal is to ensure that the requirements of digital publishing can be answered, when in scope, by the Recommendations published by W3C. This group is not chartered to publish Recommendations; instead, the goal is to cooperate with the relevant W3C Working Groups to ensure that the requirements of this particular community are met.
The mission of the HTML5 Chinese Interest Group is to facilitate focused discussion in Chinese of the HTML5 specification and of specifications closely related to HTML5, to gather comments and questions in Chinese about those specifications, to collect information about specific use cases in Chinese speaking region for technologies defined in those specifications, and to report the results of its activities as a group back to the HTML Working Group, as well as to other relevant groups and to the W3C membership and community.

The mission of the Web Payments Interest Group is to provide a forum for Web Payments technical discussions to identify use cases and requirements for existing and/or new specifications to ease payments on the Web for users (payers) and merchants (payees), and to establish a common ground for payment service providers on the Web Platform. The overall objective of this group is to identify and leverage the conditions for greater uptake and wider use of Web Payments through the identification of standardization needs to increase interoperability between the different stakeholders and the different payment methods.
W3C has created Community and Business Groups to meet the needs of a growing community of Web stakeholders. Community Groups enable anyone to socialize their ideas for the Web at the W3C for possible future standardization. Business Groups provide companies anywhere in the world with access to the expertise and community needed to develop open Web technology. New W3C Working Groups can then build mature Web standards on top of best of the experimental work, and businesses and other organizations can make the most out of W3C's Open Web Platform in their domain of interest.
