Are you still facing any issues?

Hi Shyam,    Can you give us some more details. What are you trying to do? What issues are you facing? What version of the DITA-OT are you working with? What plugin are you trying to use? Are you extending this plugin, or using it OOTB?   Thanks,    Leroy

Can you send me a screenshot of your conkeyref in source mode? When I try to add a <p>, I get an error message.      Also, <ph> is allowed in some contexts within the prolog.     

Hi there,    By rule, <p> is not allowed in the prolog.  It is meant for topic-level metadata.  Try creating a keydef that uses one of the allowed elements within prolog. Then you should be able to conkeyref that element.     I hope this helps.
