How to write data within DOCTYPE

Hi Team,

Could anyone of you let me know, how write data within DOCTYPE.

 

INPUT

<doc>

<bdy>

<img src="gr1.jpg"/>

<img src="gr2.jpg"/>

<img src="gr1.jpg"/>

</doc>

 

OUTPUT

<!DOCTYPE chapter SYSTEM "temp.dtd"[

<!ENTITY gr1 SYSTEM "gr1" NDATA IMAGE>

<!ENTITY gr2 SYSTEM "gr2" NDATA IMAGE>]>

<chapter>

xxx

</chapter>

 

XSLT

<xsl:output method="xml" doctype-system="temp.dtd"[???]>

 

Thanks
