xslt transformation with parameters

Hi ,

I've a problem to retrieve an answer from the stylesheet processors (Xalan/saxon).

here is the start point
I want always get the default section 'param' parameter, and if the 'delcode' parameter matches the specific delivery print the 'param' parameter of
the specific section.

xml:
<?xml version="1.0" encoding="UTF-8"?>
<deliveries xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="deliveries.xsd">

</xsl:stylesheet>

if i use sabcmd everything works right:
./sabcmd deliveries_param.xsl  deliveries.xml \$param=DO_STRESS \$delcode=_M

output:
      DO_STRESS=y   # from default
      DO_STRESS=n   # from _M

but each other i tested fails:
   Xalan ... -p param 'DO:STRESS' -p delcode '_M'
   java -cp xalan.jar org.apache.xalan.xslt.Process  -IN deliveries.xml -XSL deliveries_param.xsl -PARAM param "'DEL_ZONE'" -PARAM delcode "'=_M'"
   java -cp saxon.jar com.icl.saxon.StyleSheet ... param=DO_STRESS delcode=_M
output:
    always print the complete default section  'NAME=VALUE'
