If so, it's news to me.

However, you may be able to do what you want in either C4 or C5 if you
use a separate "root" dll for each dictionary. Don't tell the rest of
your app about the extra roots. Let them be "private" to dlls which use
that dictionary. The links go something like this:


    Dict_A - Root_A - DLL_A1 - DLL_A2 - ... - EXE
                        |                      |
    Dict_B > Root_B - DLL_B1                   |
                                               |
    Dict_C > Root_C - DLL_C1 - DLL_C2 ----------

In each case, the root dll will have the necessary derived objects to
handle the files of the corresponding dictionary. However, you will only
be able to "see" these from dlls in that particular chain, so any access
needs to be through procedures in that chain.

Yes, you will have multiple copies of some class methods.

No, I don't think it will hurt.

Yes, I wish they'd come up with a better way.
