The reference binding invoker can implement the "allowsPassByReference()" to
return conditionally. Are you looking for the dynamicity at the per
invocation level (i.e., need to check the Message)?
As I said before, the client (such as the proxy handler or service listener)
of the invocation chain should decide if the PBVInterceptor (should be
refactored into a utility) should be used to copy the data.
Thanks,
Raymond

Yes I can envision some useful transforms which wrapper/unwrapper data
formats without doing copies.
That raises the question of how to turn off PBVInterceptor dynamically.
I guess I hadn't given this enough thought before, since actually I'd
like to be able to do the same from the binding impl... I'd like to,
dynamically at invocation time, be able to turn off the
PBVInterceptor.
It seems like we could use a setter on the chain itself to do this.
Then we still have the question of how to turn off the copy or not for
particular data transforms. I agree turning it off
is a good default, but it seems like it should be a possible for a
particular transform to, even dynamically, decide
that, as far as it knows anyway, the PBVInterceptor copy may still be
needed.
What do you think?

Is that always a correct assumption? I thought that it could depend on
the nature of the transformation. Some transforms would copy or protect
the data, some wouldn't...
