[xsl] Moving stylesheet from Java Saxon to .NET Saxon

["Mark Wilson pubs@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

I have always used the Java version of Saxon but have been asked to 
supply a .Net version of a stylesheet and Windows batch file. I have 
never used .NET. Can anyone tell me what has to change to do this? 
Obviously, the call to Java must change, but how, and what else?
The batch file and stylesheet are below.

    Select and concat content.subject elements matched with priref 
element.
    Construct output csv file name from input xml file name.
    Requires Saxon 9.7 HE (Java version)

    Programming assumptions:
        Input XML is well formed,
        <priref> element appears once in <record> element and always 
before <content.subject> element
        No other elements appear between <content.subject> elements
  -->

    <!-- Discard lines resulting from unwanted records -->
    <xsl:strip-space elements="*"/>

documents in the xml child directory
