                        <name>Param1
                        </name>
                </parameter>
                <parameter>
                        <name>Param2

                <parameter>
                        <name>Param4

Destination expected:

  <?xml version="1.0" encoding="UTF-16" ?> 
- <parameters xmlns:fo="http://www.w3.org/1999/XSL/Format";>
  <parameter gridx="0" gridy="0">Param1</parameter> 
  <parameter gridx="0" gridy="1">Param2</parameter> 
  <parameter gridx="1" gridy="0">Param3</parameter> 
  <parameter gridx="1" gridy="1">Param4</parameter> 
  <parameter gridx="2" gridy="0">Param5</parameter> 
  </parameters>

But the result is :

  <?xml version="1.0" encoding="UTF-16" ?> 
- <parameters xmlns:fo="http://www.w3.org/1999/XSL/Format";>
  <parameter gridx="0" gridy="0">Param1</parameter>

  <parameter gridx="1" gridy="0">Param1</parameter> 
  <parameter gridx="1" gridy="1">Param1</parameter> 
  <parameter gridx="2" gridy="0">Param1</parameter> 
  <parameter gridx="2" gridy="1">Param1</parameter> 
  <parameter gridx="0" gridy="0">Param2</parameter> 
  <parameter gridx="0" gridy="1">Param2</parameter>

  <parameter gridx="1" gridy="1">Param2</parameter> 
  <parameter gridx="2" gridy="0">Param2</parameter>

  <parameter gridx="1" gridy="1">Param3</parameter> 
  <parameter gridx="2" gridy="0">Param3</parameter> 
  <parameter gridx="2" gridy="1">Param3</parameter> 
  <parameter gridx="0" gridy="0">Param4</parameter> 
  <parameter gridx="0" gridy="1">Param4</parameter> 
  <parameter gridx="1" gridy="0">Param4</parameter> 
  <parameter gridx="1" gridy="1">Param4</parameter> 
  <parameter gridx="2" gridy="0">Param4</parameter> 
  <parameter gridx="2" gridy="1">Param4</parameter> 
  <parameter gridx="0" gridy="0">Param5</parameter> 
  <parameter gridx="0" gridy="1">Param5</parameter> 
  <parameter gridx="1" gridy="0">Param5</parameter> 
  <parameter gridx="1" gridy="1">Param5</parameter> 
  <parameter gridx="2" gridy="0">Param5</parameter> 
  <parameter gridx="2" gridy="1">Param5</parameter> 
  </parameters>

Thanks in advance,
