Per Ian Hickson's request, first of my notes on the current HTML 5 draft Section 1.6.3, where you compare HTML5 with XHTML2 and XForms, you write "However, XHTML2 and XForms lack features to express the semantics of many of the non-document types of content often seen on the Web. For instance, they are not well-suited for marking up forum sites, auction sites, search engines, online shops, mapping applications, e-mail applications, word processors, real-time strategy games, and the like. This specification aims to extend HTML so that it is also suitable in these contexts." This sounds more like marketing speak than something one would find in a specification. If it's important for an individual to know why they might want to use HTML5 over XHTML2, then the information should be given in detail, rather than in one vague paragraph. In addition, I've not found that the HTML5 specification answers the claims given in the above paragraph. For instance, why would HTML5 be better for a mapping application than XHTML2? Or an auction site? In section 1.7, you write "The "DOM5 HTML", "HTML5", and "XHTML5" representations cannot all represent the same content. For example, namespaces cannot be represented using "HTML5", but they are supported in "DOM5 HTML" and "XHTML5". Similarly, documents that use the noscript feature can be represented using "HTML5", but cannot be represented with "XHTML5" and "DOM5 HTML". Comments that contain the string "-->" can be represented in "DOM5 HTML" but not in "HTML5" and "XHTML5". And so forth." "And so forth", is not something one wants to read in a specification, because we expect precision, and "and so forth" is vague, and imprecise. Since the HTML5 supposedly represents both a HTML and a XHTML serialization technique, perhaps the document can take a lesson from the RDF community and provide a separate document, or at least a section detailing the two different serialization techniques. This would go far, too, in clearing up the confusion regarding XHTML. Too many people are making assumptions that "XHTML is dead" because the XHTML serialization of HTML5 is not spelled out as clearly as it could be. You actually do mix the differences between the two throughout the document, but that, to me, seems to 'clutter' up the spec -- making it difficult to determine what's new in the spec. If the HTML5 document is a new model for web page markup, then the model aspect of the spec should be detailed separately from its various serializations, and that includes any API. Right now, it's difficult to read the specification because it jumps too frequently between the abstract and the implementation, sometimes in one sentence. More later. Shelley
