This issue appears quite often.  
For example, in the "Simpler Syntax" document that Tim Berners-Lee 
posted ( http://www.w3.org/DesignIssues/Syntax ) he included a section 
discussing this "Identifiers - what is identified?".  
Is it that, in contrast to C, etc, XML appears to be missing a syntax element 
to indicate to a user agent that the identifier should be dereferenced?
