This feature (PostScript XObjects) is deprecated since PDF 1.2:

<quote src=pdf 1.2 spec>
PostScript XObjects should be used with extreme caution and only
to obtain results not otherwise possible in PDF. Inappropriate
use of PostScript XObjects can cause PDF files to print

<quote src=pdf 1.3 reference>
Note: Since PDF 1.3 encompasses all of the Adobe imaging model
features of the PostScript language, there is no longer any
reason to use PostScript XObjects. This feature is likely to be
removed from PDF in a future version.

It's still in the 1.4 reference, but with the same warning.
