XML to INI converter generates empty value for parameter SystemPropertyFiles

Current Situation

• We assume that a protocol fragment is configured with a system property file

        <HTTPFragment name="myHTTPFragment">
          ...
          <SystemPropertyFiles>
            <SystemPropertyFile><![CDATA[/path/to/http.properties]]></SystemPropertyFile>
            <SystemPropertyFile><![CDATA[/path/to/http2.properties]]></SystemPropertyFile>
          </SystemPropertyFiles>
        </HTTPFragment>
  

• The XML to INI converter generates an empty system_property_files parameter

  [protocol_fragment_http@myHTTPFragment]
  protocol               = http
  ...
  system_property_files  = 
  

Desired Behavior

• The XML to INI converter should generate a semicolon separated list of system property files

  [protocol_fragment_http@myHTTPFragment]
  protocol               = http
  ...
  system_property_files  = /path/to/http.properties;/path/to/http2.properties
