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
