Another data point: Brother B205 doesn't print it either.
But would all of these use the same licensed PDF renderer...

On above Brother B205, this document:

\starttext
\externalfigure[foo.mkxl.pdf]
\stoptext

only prints the page number of the outer document, which is kept in a
seperate font:

NREXLC+LMRoman12-Regular             CID Type 0C       Identity-H       yes yes yes      5  0
CLLXEY+LMRoman12-Regular             CID Type 0C       Identity-H       yes yes yes      8  0

I tried converting the pdf with pdfjam (which uses pdfTeX internally)
before, which probably uses similar mechanisms, and it didn't work
either.
