I forgot to follow up on this, so here is a reiteration of my original
question: AUValidation does not report the read-only parameter in Apple's
AUPeakLimiter, and I am wondering why.
I understand the response below, that I should declare a read-only parameter.
This is something I've done with AUs in the past, but I just never checked
them in AudioUnitHosting to see if they enable that nice generic meter. My
first hunch, before writing to the list, was that the meter was created to
match a read-only parameter, and I attempted to use AUValidation to confirm
this. Is there any reason why AUValidation is not showing the read-only
parameter(s) in Apple's AUs?

Just declare the parameter as read only... its defined as a param flag
(read/write/meta/etc...)

Its supported as part of the generic view that is shipped by Apple for
any AU. Logic uses its own version of this
