Right, as long as your client library is 3.14.12 and you're using the dynamic 
array sizing feature (which is still rare since it's a new feature).  However 
I believe the client library clips all array get and subscription requests to 
the array's native element count (or maybe it rejects them if too large, I 
forget which), so I'm pretty sure that a client application using an older 
library version against an unpatched 3.14.12 IOC isn't going to be able to 
override the incorrect native count.  I haven't tried it though, so I might be 
wrong.
