New perspectives on html xhtml and xml comprehensive
Past News. What is HTML? These conventions require that the System Identifier must include a revision number. This revision number is ONLY incremented when a revision is not backward compatible. If the Working Group identifies a problem with an implementation, and it is possible to solve the problem in a way that is percent backward compatible, then the version in the group's space will be updated in place and an announcement will be sent to the XHTML 2 public email list.
The XHTML 2 Working Group states that the term "backward compatible" should be used only when: The external interface to the module cannot change in any way that would break another module or markup language, either within or outside of the W3C. The content model cannot change in any way that would cause a previously valid document to become invalid. XML Events Note. A second release was issued on 24 April with changes limited to editorial corrections.
This specification has now been superseded by HTML 4. HTML 3. HTML 2. It set the standard for core HTML features based upon current practice in Other Public Drafts The current editors' drafts of all specifications are linked to from a separate drafts page. HLink The HLink module defined in this specification provides XHTML Family Members with the ability to specify which attributes of elements represent Hyperlinks, and how those hyperlinks should be traversed, and extends XLink use to a wider class of languages than those restricted to the syntactic style allowed by XLink.
Adding a touch of style by Dave Raggett is a short guide to styling your Web pages.
A question of style sheets. For most people the look of a document - the color, the font, the margins - are as important as the textual content of the document itself. But make no mistake! HTML is not designed to be used to control these aspects of document layout. What you should do is to use HTML to mark up headings, paragraphs, lists, hypertext links, and other structural parts of your document, and then add a style sheet to specify layout separately, just as you might do in a conventional Desk Top Publishing Package.
That way, not only is there a better chance of all browsers displaying your document properly, but also, if you want to change such things as the font or color, it's really simple to do so. See the Touch of style. FONT tag considered harmful! Many filters from word-processing packages, and also some HTML authoring tools, generate HTML code which is completely contrary to the design goals of the language. HTML documents are supposed to be structured around items such as paragraphs, headings and lists.
See a Problem?
Yet some of these documents barely have a paragraph tag in sight! Make your pages readable by those with disabilities. The Web is a tremendously useful tool for the visually impaired or blind user, but bear in mind that these users rely on speech synthesizers or Braille readers to render the text. Sloppy mark-up, or mark-up which doesn't have the layout defined in a separate style sheet, is hard for such software to deal with. Wherever possible, use a style sheet for the presentational aspects of your pages, using HTML purely for structural mark-up.

Palme et al. March There are some subtle footnotes and parentheticals [in Hickson's article] indicating that the harmfulness only applies to authors that don't know the pitfalls of this practice, but much like the "Do not eat" label on the little packets of silica gel, Ian's advisory seems to be common sense and not worth mentioning to any author who actually knows what XHTML is and how to write it.
To prove this, I'll flesh out the myth for you and then show you why XHTML is the best thing since sliced bread, when it comes to our fight for Web Standards. Archived from the original on Some things are clearer with hindsight of several years. It is necessary to evolve HTML incrementally. The attempt to get the world to switch to XML, including quotes around attribute values and slashes in empty tags and namespaces all at once didn't work.
The large HTML-generating public did not move, largely because the browsers didn't complain. Some large communities did shift and are enjoying the fruits of well-formed systems, but not all. It is important to maintain HTML incrementally, as well as continuing a transition to [a] well-formed world, and developing more power in that world. It will have a different chair and staff contact. We have strong support for this group, from many people we have talked to, including browser makers.
