The EBU stance on takeout doubles (not that I'm on the L&E committee, but I have had cause to ask several related questions) seems to be: if it's expected that partner will bid (other than on hands which are making a penalty pass on their own hands), then it's a takeout double. The spectrum seems to be "how often is partner expected to bid vs how often are they expected to pass", with penalty doubles being "they will always pass" (except in abnormal cases) and takeout doubles "they will always bid" (except in abnormal cases) and so-called "optional" doubles half way between. The actual shape of the hand making the double never seems to be relevant.
The alertability has two states: double of a suit - purely takeout is not alertable, everything else is. Double of NT - purely penalties is not alertable, everything else is.
I've asked that the L&E committee consider adding "highly unusual meanings" to the alertability of otherwise non-alertable doubles, which I think doubling on a balanced 9 count would certainly cover. Given how long it's taken them to retrain people after the 2006 change to alerting of doubles (simpler, but in some cases less intuitive) they are understandably reluctant to change it again and so my request was turned down, although I believe they may be revisiting the issue soon. Hence, provided this double is legal, it's certainly not alertable.
11N3 says "near opening values". Like other places in these regs, this is a little ambiguous. I would open balanced 9 counts in some positions and vulnerabilities, but that is the absolutely permitted minimum. Does that mean doubling on a flat 7 count is "near opening values"? I suspect what is meants is "near 12" - so 10 or 11, but it's hard to justify from reading the regulations.
In any case I think it should be listed in the "other aspects of system that opponents should note" on the front of their convention card, since it is unusual, even if it's not alertable and as a TD would be very tempted to rule that they were guilty of insufficient disclosure if they had not done so. I might also suggest that if they were to alert it anyway, everyone concerned would be happier.
