Thanks John and Bill for making an interp paper. I haven't got a chance
to do it myself.
Cheers,

Hi John,
Somewhere you need a line
"References: 10-007"
so that the cited subclause and page numbers have a context for a future
reader.
Also, I would enhance the answer with more explanation:
"No. This restriction contradicts 12.5.2.4 para 13 [294:28-31] which
does allow the example program. Edits are supplied to remove the
inconsistency."
Cheers,
Bill
