Getting a PDF in an xstring format in the ABAP environment

Question

I am trying to create a PDF in ABAP reusing the ADS/SFP functionality that I can send to XI without saving the pdf first to a file (i.e. Getting the PDF in an xstring format or similar that can be put into an XML structure).
I've gone as far as to see that the class CL_FP_PDF_OBJECT appears to support returning an xstring; but does anyone have an example of how to work directly with this class or if there is a higher level class that can assist in this manner?
Note - My aim is to be able to generate reports online plus using the same form, be able to send the file through XI to be stored in Documentum (file store).
Regards,
Matt

Hi All,
  excuse me if I send you a new request, but I'm developing an interface by XI in order to create a XML with a TAG <spool> containing a PDF file of an invoice printform. I create a proxy that is called after the printform creation (by a standard smartforms) using the OTF data released from FORM_CLOSE w/o the spool generation (get_otf parameters set to 'X'). after I create a message mapping that compose the final XML and send it to receivers.
  My problem is related to the data type of my tag <spool>. my XSD schema output needs a xsd:based64Binary type. when I generated the proxy the system send a warning message ("The XSD type base64Binary does not exactly correspond to the ABAP type RAWSTRING  Message no. SPRX067). When the data is passed from proxy to XI, every 77 characters, system inserts a CR/LF.
  It's correct use a proxy?
  in order to convert the OTF data to the based64 string I used:
   CALL FUNCTION 'CONVERT_OTF_2_PDF'
    IMPORTING
      bin_filesize           = lv_numbytes
    TABLES
      otf                    = i_otfdata
      doctab_archive         = ls_doctab_archive
      lines                  = lt_line
Funzione per codifica in base64
  CALL FUNCTION 'SSFC_BASE64_CODE'
    EXPORTING
      decode                       = ' '
      io_spec                      = 'T'
      ostr_input_data_l            = lv_numbytes
    TABLES
      ostr_input_data              = lt_line
      ostr_digested_data           = pdf_based64
    EXCEPTIONS
thank you in advance,
