Currently, there is no “version” element or attribute to reflect the current version of Atom using in an Atom feed. Does it mean that there will not be any new version of Atom?
On the other hand, the specification mentioned “If the value of "type" is "xhtml", the content of atom:content MUST be a single XHTML div element and SHOULD be suitable for handling as XHTML.”. At the moment, both XHTML 1.0 and 1.0 are sharing the same XML Namespace of http://www.w3.org/1999/xhtml. However, XHTML 2.0 will have a new namespace http://www.w3.org/2002/06/xhtml2/, and the chance of having more future versions of XHTML cannot be eliminated. Have Atom prepared for this? Franklin Tse
