One mapping program for three diferent enviroments

Question

Hello there,
I have developed a scenario in which an rfc requests a web service trough XI. In the process a BPM is involved together with some XSLT mappings.
     R3->XI->WebService
The Web service request message looks like follows:
<?xml version="1.0" encoding="UTF-8"?>
<cem:Z_ORDER_SEARCH xmlns:cem="http://XXXXXXXX/yyyyyyyyyyyy">
     <messageStructure/>
</cem:Z_ORDER_SEARCH>
Where "http://XXXXXXXX/yyyyyyyyyyyy" Is the web service destination.
Everything works fine, but as I have to manage three different environments for Development, Quality and Production I need three different versions of the XSL mapping since destinations are not the same for Dev, Qlty and Production environments.
I found out that I can get information of the sender using runtime parameters as follows:
<xsl:param name="SenderSystem">
I would like to evaluate this information to determine the target URL destination.
If the sender is the development sender then the URL target is the development destination and so on.
I tried the following code:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:cemDev="http://developmentDestination"
xmlns:cemQlty="http://qualityDestination"
xmlns:cemPrd="http://productionDestination"
xmlns:cem=""
<xsl:namespace-alias stylesheet-prefix="cem" result-prefix="cemDev"/>
<xsl:template match="/">
     <cem:mappingProgram/>
</xsl:template>
</xsl:stylesheet>
This works all right, but I cannot insert code to evaluate the destination.
On the other hand, this code is not valid:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:cemDev="http://developmentDestination"
xmlns:cemQlty="http://qualityDestination"
xmlns:cemPrd="http://productionDestination"
xmlns:cem="">
<xsl:param name="SenderSystem"/>
     <xsl:choose>
          <xsl:when test="string($SenderSystem) = 'PRODUCTION'">
               <xsl:namespace-alias stylesheet-prefix="cem" result-prefix="cemPrd"/>
          </xsl:when>
          <xsl:when test="string($SenderSystem) = 'QUALITY'">
               <xsl:namespace-alias stylesheet-prefix="cem" result-prefix="cemQlty"/>
          </xsl:when>
          <xsl:otherwise>
               <xsl:namespace-alias stylesheet-prefix="cem" result-prefix="cemDev"/>
          </xsl:otherwise>
     </xsl:choose>
     <xsl:template match="/">
          <cem:mappingProgram/>
     </xsl:template>
</xsl:stylesheet>
Neither this one:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:cemDev="http://developmentDestination"
xmlns:cemQlty="http://qualityDestination"
xmlns:cemPrd="http://productionDestination"
xmlns:cem="">
        <xsl:param name="SenderSystem"/>
        <xsl:template match="/">
     <xsl:choose>
          <xsl:when test="string($SenderSystem) = 'PRODUCTION'">
               <xsl:namespace-alias stylesheet-prefix="cem" result-prefix="cemPrd"/>
          </xsl:when>
          <xsl:when test="string($SenderSystem) = 'QUALITY'">
               <xsl:namespace-alias stylesheet-prefix="cem" result-prefix="cemQlty"/>
          </xsl:when>
          <xsl:otherwise>
               <xsl:namespace-alias stylesheet-prefix="cem" result-prefix="cemDev"/>
          </xsl:otherwise>
     </xsl:choose>
     <cem:mappingProgram/>
      </xsl:template>
</xsl:stylesheet>
I tried this other code, which is obviously not valid:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
     <xsl:template match="/">
          <xsl:param name="SenderSystem"/>
          <xsl:choose>
               <xsl:when test="string($SenderSystem) = 'PRODUCTION'">
                    <cem:Z_ORDER_SEARCH xmlns:cem="http://productionDestination">
               </xsl:when>
               <xsl:when test="string($SenderSystem) = 'QUALITY'">
                    <cem:Z_ORDER_SEARCH xmlns:cem="http://qualityDestination">
               </xsl:when>
               <xsl:otherwise>
                    <cem:Z_ORDER_SEARCH xmlns:cem="http://developmentDestination">
               </xsl:otherwise>
          </xsl:choose>
     <cem:mappingProgram/>
</cem:Z_ORDER_SEARCH>               
     </xsl:template>
</xsl:stylesheet>
So the only way I found to make it works is like this:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
     <xsl:template match="/">
          <xsl:param name="SenderSystem"/>
          <xsl:choose>
               <xsl:when test="string($SenderSystem) = 'PRODUCTION'">
                    <cem:Z_ORDER_SEARCH xmlns:cem="http://productionDestination">
     <cem:mappingProgram/>
                    </cem:Z_ORDER_SEARCH>
               </xsl:when>
               <xsl:when test="string($SenderSystem) = 'QUALITY'">
                    <cem:Z_ORDER_SEARCH xmlns:cem="http://qualityDestination">
     <cem:mappingProgram/>
                    </cem:Z_ORDER_SEARCH>
               </xsl:when>
               <xsl:otherwise>
                    <cem:Z_ORDER_SEARCH xmlns:cem="http://developmentDestination">
     <cem:mappingProgram/>
                    </cem:Z_ORDER_SEARCH>               
               </xsl:otherwise>
          </xsl:choose>
     </xsl:template>
</xsl:stylesheet>
Unfortunately this doesn’t solve my problem, because I need to reproduce the mapping program three times in the document.
Any ideas, or suggestions how to manage one mapping program for the three different environments?
Thanks a lot in advance, Raú

Hi there,
I just found one way of getting this done. It may not be the better waw, but I post it in case it is helpfull.
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format">
     <!-- Sender System at runtime-->
     <xsl:param name="senderSystem"/>
     <!-- SenderSystem constants (development addressed by default)-->
     <xsl:variable name="qualitySenderSystem" select="'WHATEVERTHENAMEOFTHEQUALITYSENDERSYSTEM'"/>
     <xsl:variable name="productionSenderSystem" select="'WHATEVERTHENAMEOFTHEPRODUCTIONSENDERSYSTEM'"/>
     <!-- Mapping program template to be called-->
     <xsl:template name="mappingProgram" match="/">
          <!-- MAPPING PROGRAM-->
          <UNIQUE_MAPPING_PROGRAM/>
          <!-- END OF MAPPING PROGRAM-->
     </xsl:template>
     <!Receiver determination depending on senderSystem>
     <xsl:template match="/">
          <xsl:choose>
               <xsl:when test="$senderSystem=$productionSenderSystem">
                    <xxx:Z_ORDER_SEARCH xmlns:xxx="http://production">
                         <xsl:call-template name="mappingProgram"/>
                    </xxx:Z_ORDER_SEARCH>
               </xsl:when>
               <xsl:when test="$senderSystem=$qualitySenderSystem">
                    <xxx:Z_ORDER_SEARCH xmlns:xxx="http://quality">
                         <xsl:call-template name="mappingProgram"/>
                    </xxx:Z_ORDER_SEARCH>
               </xsl:when>
               <xsl:otherwise>
                    <xxx:Z_ORDER_SEARCH xmlns:xxx="http://development">
                         <xsl:call-template name="mappingProgram"/>
                    </xxx:Z_ORDER_SEARCH>
               </xsl:otherwise>
          </xsl:choose>
     </xsl:template>
</xsl:stylesheet>
