DOCTYPE declaration with an external entity

We are creating a NewsML/NITF doc out of our process.  The header of this
document needs to contain an entity statement.  The very top of this
document should look like this:

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE NewsML SYSTEM "http://nationaljournal.com/dtd/NewsML_1.2.dtd" [
<!ENTITY % nitf SYSTEM "http://nationaljournal.com/dtd/nitf-2-5.dtd">
%nitf;
]> 


Currently I have been pulling the <!DOCTYPE> in by using a <doctype-system>
child tag of serializer:


<!-- 03.09.05.df newsml serializer -->
    <map:serializer logger="sitemap.serializer.xml" mime-type="text/xml"
          name="newsml" src="org.apache.cocoon.serialization.XMLSerializer">
        <cdata-section-elements>p ul</cdata-section-elements>
        <doctype-system>
           http://nationaljournal.com/dtd/NewsML_1.2.dtd
        </doctype-system>
        <encoding>UTF-8</encoding>
    </map:serializer>
<!-- 03.09.05.df END newsml serializer -->

I've scoured the web looking for an answer, but have come up short.  Any
ideas on how to accomplish this?

Best,
David

Hi,

Not an advisable approach in Cocoon (SAX) context, and only working in the case you don't need that 
doctype info inside Cocoon:

Use an XSL to add prolog info with <xsl:text disable-output-escaping="yes">..

Not advisable because the text is not 'unescaped' until actually serialized.

Cheers,
Geert

Thank you for the input Conal.  That is definitely on way to handle the
problem!  We were hoping to have a solution that would generate the same
output as the listing given since we have been generating content with that
header - for consistency - but this would seem to definitely work.

Thanks again for your time and interest!

Best,

David

I don't know about how to serialize your XML with an internal DTD (to
include the nitf-2-5.dtd).

But it seems to me you could define a 3rd DTD file, consisting simply of
references to the NewsML and NITF DTDs, and use THAT DTD file as doctype.
i.e. you'd be amalgamating these two DTDs using a 3rd (external) DTD, rather
than trying to do it using the internal DTD in your instance documents.

HTH!
