which means that you have to make the "id" attribute mandatory for  
this purpose. If I follow you, because a dfn alone would be useless?

Good: Another use case to add to the specification.

So is it a requirement for implementation for user agent?
Not said in the specification.

All the interesting comments made since the start shows that there is  
a lack of

     - practical examples
     - implementation requirement
     - semantic model definition
     - use cases

One or more of those items in the list in the specification and/or a  
best practices guide for XHTML 2.0. Because right now, many people  
(webmasters, users, etc) don't understand it, including me on many  
things. :)

ok. Fair enough at the light of the comments.

except that to know what part of the definition is useful to  
understand the term makes it very difficult without a container. Al  
Gilmann made a very good comment accessibility wise for example.

;)
Maybe a wiki project could be used to create the use case for each  
element on this element and that would be the start of a best  
practice guide.

thanks again.
