how to create a table-part header?

["Koblizek, Vaci" <Vaci-Koblizek@xxxxxxxxxx>]

I'm struggling through my first attempt to create a table in an rtf document
using DSSSL. I'm trying to follow the documentation in 
http://sunsite.unc.edu/pub/sun-info/standards/dsssl/dssslo/do960816.htm ,
but I'm stuck as to how to get my "HEADING" element to flow into the "header
port" of the table-part flow object, as indicated by this description:

"A table-part flow object is allowed only within a table flow object. A
table-part flow object has three ports: 

      the principal port is used for the table body. 
      header is used for the table header. 
      footer is used for the table footer."

Should I be tagging my header element somehow to get it flow into the
non-default object?

My test data is as follows:

testdoc.dtd:

<!ELEMENT testdoc   -    -     (table)   >
<!ELEMENT table     -    -      (tablepart)*     >
<!ELEMENT heading   -    -    (#PCDATA)        >
<!ELEMENT tablepart -    -     (heading?, row*)      >
<!ELEMENT summary   -    -  (#PCDATA)        >
<!ELEMENT row       -    -     (cell+)          >
<!ELEMENT cell      -    -     (#PCDATA)        >

testdoc.dsl:

(element TESTDOC
	 (make sequence           
	       font-family-name: "Arial"
	       input-whitespace-treatment: 'collapse
	       quadding: 'start
	       (process-children)))

(element TABLE
	 (make table
	       (process-children))) 
	       
(element TABLEPART
	 (make table-part	       
	       (process-children)))   

(element ROW
	 (make table-row
	       (process-children)))

(element CELL
	 (make table-cell
	       (process-children)))


testdoc.xml:

<?xml version="1.0"?>
<!DOCTYPE testdoc SYSTEM "testdoc.dtd">
<testdoc>
  <table>
    <tablepart>
      <heading>Part of the table</heading>
      <row><cell>A</cell><cell>B</cell></row>
    </tablepart>
  </table>
</testdoc>
