CGIDEV2 XML Section Not Found

I'm trying to create an XML document using CGIDEV2.

My first section is coming up incomplete.
All other sections are not coming out at all.
The latter sections, I'm getting the message in CGIDEBUG:

WrtSection: Section AUTH not found.
(for every other section.)

My XML source (OPXMLBCH) looks like this:

<AS400>TOP
<?xml version="1.0" encoding="UTF-8"?>
<transRequest RequestCount=/%OCOUNT%/>
<AS400>AUTH
<newOrder BatchRequestNo=/%OCBCH#%/>
<industryType>/%OCINDS%/</industryType>
<transType>/%OCTRTP%/</transType>
</newOrder>
<AS400>MARK
<markForCapture BatchRequestNo=/%OCBCH#%/>
<txRefNum>/%OCTREF%/</txRefNum>
</markForCapture>
<AS400>ENDDAY
<endOfDay BatchRequestNo=/%OCBCH#%/>
<bin>/%OCCBIN%/</bin>
<merchantID>/%OCMRID%/</merchantID>
<terminalID>/%OCTRID%/</terminalID>
</endOfDay>
<AS400>BOTTOM
</transRequest>


In my RPG program I'm doing this:

DocName = 'OPXMLBCH';
callp gethtml('HTMLSRC': '*LIBL' : DocName: '<AS400>');
CodePage = 819;
callp UpdHtmlVar('OCOUNT':OCOUNT);
callp wrtsection('TOP');

I loop through the various sections, doing a callp to UpdHtmlVar for all my variables and then calling
Wrtsection for each:

callp wrtsection('AUTH');

And then at the end

rc = WrtHtmlToStmf(XML_Output:CodePage);

All I get in the file is PART of Top, specifically:

<?xml version="1.0" encoding="UTF-8"?>

I don't get my <transRequest RequestCount=/%OCOUNT%/> line...

And every other section it says "WrtSection: Section AUTH not found." in CGIDEBUG.

Has anyone seen this?
Any suggestions?

Thanks,
Charlie
