Problems with output of a bpel process

Question

Hi,
I have a process with the following schema:
<schema attributeFormDefault="qualified"
     elementFormDefault="qualified"
     targetNamespace="http://xmlns.oracle.com/BPELProcess1"
     xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:tns="http://xmlns.oracle.com/BPELProcess1">
     <element name="BPELProcess1ProcessRequest">
          <complexType>
               <sequence>
                    <element name="marca" type="string"/>
               </sequence>
          </complexType>
     </element>
     <element name="BPELProcess1ProcessResponse">
          <complexType>
               <sequence>
                    <element name="carros" type="tns:carros"/>
               </sequence>
          </complexType>
     </element>
<complexType name="carro">
<sequence>
*<element name="DONO" type="decimal"/>*
<element name="MATRICULA" type="string"/>
<element name="MARCA" type="string"/>
</sequence>
</complexType>
<complexType name="carros">
<sequence>
<element name="carro" minOccurs="0" maxOccurs="unbounded" type="tns:carro"/>
</sequence>
</complexType>
</schema>
Then I transform the output data from a DB Adapter to my BPELProcess1ProcessResponse with the following transformation:
<?xml version="1.0" encoding="UTF-8" ?>
<?oracle-xsl-mapper
<!-- SPECIFICATION OF MAP SOURCES AND TARGETS, DO NOT MODIFY. -->
<mapSources>
<source type="XSD">
<schema location="carrosORCL.xsd"/>
<rootElement name="carrosORCLOutputCollection" namespace="http://xmlns.oracle.com/pcbpel/adapter/db/carrosORCL"/>
</source>
</mapSources>
<mapTargets>
<target type="XSD">
<schema location="BPELProcess1.xsd"/>
<rootElement name="BPELProcess1ProcessResponse" namespace="http://xmlns.oracle.com/BPELProcess1"/>
</target>
</mapTargets>
<mapGenType type="ALL"/>

?>
<xsl:stylesheet version="1.0" xmlns:tns="http://xmlns.oracle.com/BPELProcess1"

exclude-result-prefixes="xsl xs ns0 tns bpws ehdr hwf xp20 xref ora ids orcl">
<xsl:template match="/">
<tns:BPELProcess1ProcessResponse>
<tns:carros>
<xsl:for-each select="/ns0:carrosORCLOutputCollection/ns0:carrosORCLOutput">
<tns:carro>
<tns:DONO>
<xsl:value-of select="ns0:DONO"/>
</tns:DONO>
<tns:MATRICULA>
<xsl:value-of select="ns0:MATRICULA"/>
</tns:MATRICULA>
<tns:MARCA>
<xsl:value-of select="ns0:MARCA"/>
</tns:MARCA>
</tns:carro>
</xsl:for-each>
</tns:carros>
</tns:BPELProcess1ProcessResponse>
</xsl:template>
</xsl:stylesheet>
The problem is that the element ns0:DONO (type=DECIMAL) from the db adapter is empty so the tag <DONO> doesn't appear in the output! Only if I "Set text = 0" in the transformation which is not a good solution.
Is there a better way to do this?
I already tried the following solution (doesn't do anything!):
"45.3.13 How to Control the Generation of Unmapped Target Elements
There are five options for controlling the generation of empty elements in the target XSL:
* Do not generate unmapped nodes (default option).
* Generate empty nodes for all unmapped target nodes.
* Generate empty nodes for all required, unmapped target nodes.
* Generate empty nodes for all nillable, unmapped target nodes.
* Generate empty nodes for all required or nillable, unmapped target nodes.
Set these options as follows:
* At the global level:
Select Tools > Preferences > XSL Maps. The global setting applies only when a map is created.
* At the map level:
Select XSL Generation Options from the map context menu. Each map can then be set independently by setting the options at the map level.
Empty elements are then generated for the selected unmapped nodes. If the unmapped node is nillable, it is generated with xsi:nil="true"."
My question is: is it possible to return the empty tag with a decimal element? If yes, how?
Kind regards!

I'm using Oracle SOA Suite 10.1.3.4.0.
Yes, I tried this transformation:
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0"
xmlns:xref="http://www.oracle.com/XSL/Transform/java/oracle.tip.xref.xpath.XRefXPathFunctions"
xmlns:xp20="http://www.oracle.com/XSL/Transform/java/oracle.tip.pc.services.functions.Xpath20"
xmlns:bpws="http://schemas.xmlsoap.org/ws/2003/03/business-process/"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ora="http://schemas.oracle.com/xpath/extension"
xmlns:ehdr="http://www.oracle.com/XSL/Transform/java/oracle.tip.esb.server.headers.ESBHeaderFunctions"
xmlns:orcl="http://www.oracle.com/XSL/Transform/java/oracle.tip.pc.services.functions.ExtFunc"
xmlns:ids="http://xmlns.oracle.com/bpel/services/IdentityService/xpath"
xmlns:hwf="http://xmlns.oracle.com/bpel/workflow/xpath"
exclude-result-prefixes="xsl xref xp20 bpws ora ehdr orcl ids hwf">
<xsl:strip-space elements="*"/>
<xsl:template match="node()[count(descendant-or-self::*string-length(.)>0])>0]|@*">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
but returned the same error:
Transformation_5.xsl
Line Number:(13) : Error: "xsl:strip-space" XSL Element Currently not Supported
Line Number:(14) : Error: <xsl:template match="/"> and <xsl:template name="..."> are the only permitted <template> elements in the XSL
But I don't want to remove the empty tags. By default the empty tags doesn't appears in output, but I want them to appear.
Regards.
