What is the best way to inform users of an XML document of its representation conventions? One approach is to inform users by adding more stuff to the XML document, e.g.,

 

<altitude units="feet" reference="mean sea level">10</altitude>

 

But now we’ve got to inform users of the representation conventions of the new stuff.

 

Yikes! We’ve entered an infinite regress.
