Bogus Export to docbook

Please detail:
- your system
- your OOo version
- what you understand with "doesn't work", "bogus", "cannot export"

Sorry for my initial post, it was indeed lacking informations. 

I am working on a debian/stable (5.0.4) system. Using openoffice 3.2:

$ apt-cache policy openoffice.org
openoffice.org:
  Installed: 1:3.2.0-4~bpo50+1
  Candidate: 1:3.2.0-4~bpo50+1

The docbook file after export does contains most information, however one can
notice that the third row does not display properly. It contains:

         <row>
            <entry>
               <para>Clinical Trial Subject</para>
            </entry>
            <entry>
               <para>C.7.1.3</para>
            </entry>
            <entry>
               <para>U</para>
            </entry>
         </row>


while it should be more like:

         <row>
            <entry>
               <para/>
            </entry>
            <entry>
               <para>Clinical Trial Subject</para>
            </entry>
            <entry>
               <para>C.7.1.3</para>
            </entry>
            <entry>
               <para>U</para>
            </entry>
         </row>


I am not a docbook expert, so there might be other tricks for a row to contains
only 3 entry elements, but the table layout should describe this layout.

Hoping to be clear this time.

Thanks !

@SUS: I couldn't find a spec for our docbook export.
Please evaluate if bug or unsupported feature.

Proposed Fixed Docbook Export

Looking into docbook details. It appears the proper fix for this is:

         <row>
            <entry morerows="1">
               <para>Patient</para>
            </entry>
            <entry>
               <para>Patient </para>
            </entry>
            <entry>
               <para>C.7.1.1</para>
            </entry>
            <entry>
               <para>M</para>
            </entry>
         </row>

Here is the local patch I am using:


$ cat /usr/lib/openoffice/basis3.1/share/xslt/docbook/sofftodocbookheadings.xsl
...
	<xsl:template match="table:table-cell">
		<xsl:element name="entry">
			<xsl:if test="@table:number-rows-spanned >'1'">
				<xsl:attribute name="morerows">
					<xsl:value-of select="number(@table:number-rows-spanned)-1"/>
				</xsl:attribute>
			</xsl:if>
