    ; The HTTP verb should be "PROPFIND"
    CkHttpRequest::setCkHttpVerb(req, "PROPFIND")

    ; The Content-Type should be "application/xml", and
    ; the charset attribute in the Content-Type header should

    ; Load the request body with the XML.  Your application 
    ; is free to construct the XML using any means desired.
