Finally We Get New Elements In HTML 5
An anonymous reader writes "Pure HTML enhancements hardly grew at all in the last eight years. Forward motion basically stopped in 1999 with HTML 4. Now the future looks bright. Recently, HTML has come back to life with HTML 5. Tons of new elements will be available for structure (article, nav, section, etc.), block semantic elements (aside, figure, dialog), and several other functions."
Page authors could use XHTML 5 (XHTML is allowed under the HTML 5 spec, which they call XHTML 5), and include an xsl style sheet that would convert these new tags to something useful in the older browsers which do not support the new tags (convert to ). That way, there is no need for users to upgrade. There are lots of other strategies for dealing with older browsers too. The answer doesn't always have to be "require users to upgrade".
