The primary goal of this group is to develop W3C Recommendations that enable multimodal interaction with various devices including desktop PCs, mobile phones and less traditional platforms such as cars and intelligent home environments. For rapid adoption on a global scale, it should be possible to add simple multimodal capabilities to existing markup languages in a way that is backwards compatible with widely deployed devices, and which builds upon widespread familiarity with existing Web technologies. The standards should be scalable to enable richer capabilities for subsequent generations of multimodal devices.

The desired outcome of more research in Web accessibility and awareness of accessibility in mainstream Web-related research should decrease the number of potential barriers in future Web-related technologies.
The Working Group is to specify a format for rules, so they can be used across diverse systems. This format (or language) will function as an interlingua into which established and new rule languages can be mapped, allowing rules written for one application to be published, shared, and re-used in other applications and other rule engines.

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.
The mission of the Web Services Policy Working Group is to produce W3C Recommendations for Web Services Policy by refining the “WS-Policy” Member Submission, addressing implementation experience and interoperability feedback from the specifications, maximizing compatibility with existing policy assertions and considering composition with other components in the Web services architecture.
The mission of the Web Services Resource Access Working Group is to produce W3C Recommendations for a set of Web Services specifications by refining the WS-Transfer, WS-ResourceTransfer, WS-Enumeration, WS-MetadataExchange and WS-Eventing Member Submissions , addressing existing issues in those specifications, implementation experience and interoperability feedback from implementers and considering composition with other Web services standards. The submitted specifications define SOAP-based mechanisms for interacting with the XML representation behind a resource-oriented Web Service, accessing metadata related to that service, as well as a mechanism to subscribe to events related to that resource.
The mission of the Web Fonts Working Group is to develop specifications that allow the interoperable deployment of downloadable fonts on the Web.

The mission of the XML Schema Working Group is to maintain and enhance the XML Schema Definition Language, an XML vocabulary for defining document classes by specifying structural and non-structural constraints on documents. XML Schema is similar to, but more expressive than, the notation given in XML 1.0 and SGML for document type definitions.
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 Semantic Sensor Network Incubator Group is to begin the formal process of producing ontologies that define the capabilities of sensors and sensor networks, and to develop semantic annotations of a key language used by services based sensor networks.
The mission of the Unified Service Description Language (USDL) Incubator Group is to define a language for describing general and generic parts of technical and business services to allow services to become tradable and consumable. Technical services are considered electronic services based on WSDL, REST or other technical specifications. Business services are defined as business activities that are provided by a service provider to a service consumer to create value for the consumer. Thus, the business services are more general and comprise manual and technical services. This enables new business models in the field of service brokerage because services can automatically be offered, delivered, executed, and composed from services of different providers.
