The problem is not the "--xtx switch", but the lack of support for the
underlying (xdvipdfmx) driver.

I googled a bit and found the following slides:
      http://project.ktug.or.kr/dvipdfmx/doc/tug2005.pdf
see page 18 in particular.

In spec-fdf there is:

\definespecial \doattachfile {\doPDFattachfile}

\def\doPDFattachfile#1#2#3#4#5#6#7#8%
  {\bgroup % title width height color symbol file
   \edefconvertedargument\PDFfile{#8}%
   % beware: the symbol may (indirectly) use the file
   % reference when typesetting the object number;
   \presetPDFsymbolappearance{#5}{#6}{#2}{#3}{#4}% sets width/height
   \startPDFsymbolappearance
     \doPDFembedfile\PDFfile{#7}{#8}%
     \doPDFgetembeddedfilereference\PDFfile\PDFobjectreference
     \setFDFlayer\@@DriverAttachmentLayer
     \doPDFannotation{\width}{\totalheight}
       {/Subtype /FileAttachment
        /FS \PDFobjectreference\space
        /Contents (#1)
        \PDFsymbol
        \FDFlayer
        \PDFattributes}%
   \stopPDFsymbolappearance
   \egroup}

Something similar needs to be added to spec-dpx.tex. (If Hans doesn't
reply, then someone else will have to.)
