Re: [xml] XML : PE reference outside DTD

Hi,
Thank you for the clarification.
I was interpreting %foo; inside document content as parameter entity, which
was wrong understanding I belive.
So, it solved my querry. Anyway I am attaching the document I have used.


Thanks & Regards,
murali

To do a Parameter-entity reference one use %name; 
  http://www.w3.org/TR/REC-xml/#dt-entref
  "[Definition: Parameter-entity references use percent-sign (%) and
   semicolon (;) as delimiters.]"

"Parameter-entity references MUST NOT appear outside the DTD."

%foo; is not a Parameter-entity reference in content:
  http://www.w3.org/TR/REC-xml/#dt-entref
  "Outside the DTD, the % character has no special significance; thus, what
would be parameter entity references in the DTD are not recognized as markup
in content."

and 

&foo; is not a Parameter-entity reference

so I didn't see a parameter entity reference in your document, but again
send a minimal one as attachement to make sure.

Daniel
