The XML Core Working Group invites implementation of the Candidate Recommendation of XML Inclusions (XInclude) Version 1.1. Many programming languages provide an inclusion mechanism to facilitate modularity. Markup languages also often have need of such a mechanism. This specification introduces a generic mechanism for merging XML documents (as represented by their information sets) for use by applications that need such a facility. The syntax leverages existing XML constructs – elements, attributes, and URI references. Learn more about the Extensible Markup Language (XML) Activity.

The Internationalization Working Group has published a Group Note of Use Cases & Exploratory Approaches for Ruby Markup. This document was designed to support discussion about what is needed in the HTML5 specification, and possibly other markup vocabularies, to adequately support ruby markup. It describes a number of use cases associated with ruby usage, and then examines a number of possible ruby markup approaches for each use case, listing pros and cons for each approach.

W3C today published the final report of the Workshop on RDF Validation: Practical Assurances for Quality RDF Data that was held 10-11 September 2013 in Cambridge.

The goal of the Workshop was to identify use cases, requirements, and candidate technologies to address the need for interface definition and validation for RDF documents and messages. The 20 presentations focused on current and future requirements and solutions. Discussion sessions focused on consensus-building around scope and next steps.

This workshop laid the groundwork for W3C to develop a human and machine-readable description of the “shape” of the RDF graphs that a service produces or consumes. This description should be usable for validation, form-generation, as well as human-readable documentation. The participants further agreed that the solution must provide a declarative way of describing simple integrity constraints along with an extension mechanism that allows using technologies such as SPARQL to specify more complex constraints.

The Cascading Style Sheets (CSS) Working Group has published a Proposed Recommendation of CSS Style Attributes. Markup languages such as HTML and SVG provide a style attribute on most elements, to hold inline style information that applies to those elements. This draft describes the syntax and interpretation of the CSS fragment that can be used in such style attributes. Comments are welcome through 31 October. Learn more about the Style Activity.

The Cascading Style Sheets (CSS) Working Group invites implementation of two Candidate Recommendations:

• CSS Cascading and Inheritance Level 3. This CSS module describes how to collate style rules and assign values to all properties on all elements. By way of cascading and inheritance, values are propagated for all properties on all elements. CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc.
• CSS Fonts Module Level 3. This CSS3 module describes how font properties are specified and how font resources are loaded dynamically. The contents of this specification are a consolidation of content previously divided into CSS3 Fonts and CSS3 Web Fonts modules. The description of font load events was moved into the CSS3 Font Load Events module.
