  Stream: TMemoryStream;
  Opts: TAssocFilesOptions;
  F: TAssociateFile;
begin
  Stream := TMemoryStream.Create;
  try
    Opts := TAssocFilesOptions.Default;
    Opts.TargetPage := 0;

    F.FileName := 'data.xml';
    F.Content := GetXmlBytes;
    F.Relationship := afData;
    F.MIMEType := 'text/xml';

    SetLength(Opts.Files, 1);
    Opts.Files[0] := F;

    if Pdf1.SaveAsWithAssociateFilesToStream(Stream, Opts) then

      Stream.Position := 0;
      SendToNetwork(Stream);
    end;
