    // We want the top-most header of our request to look like this:

    // Content-Encoding: gzip
    // Accept-Encoding: gzip,deflate
    // Content-Type: multipart/related; type="application/xop+xml";
    //    start="<rootpart@soapui.org>"; start-info="text/xml"; boundary="----=_Part_3_19706996.1467294979823"
    // SOAPAction: "http://www.bafin.de/mvp/a26mifir/submitDATTRA"
    // MIME-Version: 1.0
    // Transfer-Encoding: chunked
    // Host: portal.mvp.bafin.de:444
    // Connection: Keep-Alive
    // User-Agent: Apache-HttpClient/4.1.1 (java 1.5)

    // Some header fields are unimportant.  
    // 1) We can omit the User-Agent.
    // 2) Also, the Transfer-Encoding doesn't need to be "chunked".  It shouldn't matter whether it's chunked or non-chunked.
    // 3) We do need the Content-Encoding to be "gzip", because the documentation at https://www.bafin.de/SharedDocs/Downloads/EN/dl_mvp-portal_soap_webservice_a26mifir_en.pdf
    // explicitly states that it wants a gzip compressed request body.
    // 4) Don't worry about specifying a boundary.  Chilkat will auto-generate a boundary and add it to the Content-Type.
    // 5) If we're sending many requests on the same connection, then set the Connection: Keep-Alive header.  Otherwise, there is no need for it.

    // Begin specifying header fields for the topmost header:
